Unicode character property

The Unicode Standard assigns various properties to each Unicode character and code point.^[1]^[2]

The properties can be used to handle characters (code points) in processes, like in line-breaking, script direction right-to-left or applying controls. Some "character properties" are also defined for code points that have no character assigned and code points that are labelled like "<not a character>". The character properties are described in Standard Annex #44.^[2]

Properties have levels of forcefulness: normative, informative, contributory, or provisional. For simplicity of specification, a character property can be assigned by specifying a continuous range of code points that have the same property.^[3]

Semantic elements

Properties are displayed in the following order:^[4]

[code];[name];[gc];[cc];[bc];[decomposition];[nv-dec];[nv-dig];[nv-num];[bm];[alias];;[upper case];[lower case];[title case]

alias = corrected name. Obsolete. Now tracked with a separate database, but remains for Unicode 1.0 names.
bc = bidi (bidirectional) category [L, R etc]
bm = bidi mirrored [N or Y]
cc = combining class [position of diacritic]
decomposition type or <mapping> = letter + diacritic, ligature X Y, superscript X, font X, initial X, medial X, final X, isolated X, vertical X, etc.
gc = general category [letter, symbol, digit, punctuation, case behaviour, etc.]
nv = numeric type and value [of a digit]. If numeric type is 'decimal', all 3 slots are filled. If 'digit', the first will be null. (This has been discontinued.) If 'numeric', then the first two will be null and only the last will be used.

The property between alias and upper case is obsolete and is now null for all Unicode characters.

Name and alias

A Unicode character is assigned a unique Name (na).^[1] The name is composed of uppercase letters A–Z, digits 0–9, hyphen-minus and space. Some sequences are excluded: names beginning with a space or hyphen, names ending with a space or hyphen, repeated spaces or hyphens, and space after hyphen are not allowed. The name is guaranteed to be unique within Unicode, and can be used to identify a code point and its character. Ideographic characters, of which there are tens of thousands, are named in the pattern "cjk unified ideograph-hhhh". For example, U+4E00 一 CJK UNIFIED IDEOGRAPH-4E00. Formatting characters also have names: U+00A0 NO-BREAK SPACE.

The following Unicode categories do not have a Name value assigned: Controls (General Category: Cc), Private use (Co), Surrogate (Cs), Non-characters (Cn) and Reserved (Cn). They may be referenced, informally, by a generic or specific meta-name, called "Code Point Labels": <control>, <control-0088>, <reserved>, <noncharacter-hhhh>, <private-use-hhhh>, or <surrogate>. Since these labels contain "<" and ">", they can never appear in a Name, which prevents confusion.

Unicode 1.0 names

In version 2.0 of Unicode, many names were changed. From then on the rule "a name will never change" came into effect, including the strict (normative) use of alias names. Disused Unicode 1.0 names were moved to the property Alias, to provide backward compatibility.

For example, U+0264 ɤ LATIN SMALL LETTER RAMS HORN has the Unicode 1.0 name "LATIN SMALL LETTER BABY GAMMA".

Character name alias

Starting from Unicode 2.0, the published name for a code point will never change. Therefore, in the event of a character name being misspelled or if the character name is completely wrong or seriously misleading, a formal Character Name Alias may be assigned to the character, and this alias may be used by applications instead of the actual defective character name.^[1] For example, U+FE18 ︘ PRESENTATION FORM FOR VERTICAL RIGHT WHITE LENTICULAR BRAKCET has the character name alias "PRESENTATION FORM FOR VERTICAL RIGHT WHITE LENTICULAR BRACKET" in order to mitigate the misspelling of "bracket" as "brakcet" [sic] in the actual character name; U+A015 ꀕ YI SYLLABLE WU has the character name alias "YI SYLLABLE ITERATION MARK" because, contrary to the character name, it does not have a fixed syllabic value.

In addition to character name aliases which are corrections to defective character names, some characters are assigned aliases which are alternative names or abbreviations. Five types of character name aliases are defined in the Unicode Standard:

Correction: corrections for misspelled or seriously incorrect character names;
Control: ISO 6429 names for C0 and C1 control functions (which are not assigned character names in the Unicode Standard);
Alternate: alternative names for some format characters (only U+FEFF ZERO WIDTH NO-BREAK SPACE which has the alias "BYTE ORDER MARK");
Figment: Documented labels for some C1 control code functions which are not actual names in any standard;
Abbreviation: Abbreviations or acronyms for control codes, format characters, spaces, and variation selectors.

All formal character name aliases follow the rules for permissible character names, and are guaranteed to be unique within both the character name alias and the character name namespaces (for this reason, the ISO 6429 name "BELL" is not defined as an alias for U+0007 <control-0007> because U+1F514 is named "BELL"; U+0007 instead has the alias "ALERT").^[1]

As of Unicode 17.0, 39 formal character name aliases are defined as corrections for defective character names.^[5]

Apart from these normative names, informal names may be shown in the Unicode code charts. These are other commonly used names for a character, and do not have the same character restriction. These informal names are not guaranteed to be unique, and may be changed or removed in later versions of the standard.

General Category

Each code point is assigned a value for General Category. This is one of the character properties that are also defined for unassigned code points and code points that are defined "not a character".

The Name remains blank, which can prevent inadvertently replacing, in documentation, a Control Name with a true Control code. Unicode also uses <not a character> for <noncharacter>.

Punctuation

Characters have separate properties to denote they are a punctuation character. The properties all have a Yes/No values: Dash, Quotation_Mark, Sentence_Terminal, Terminal_Punctuation. The Punctuation property refers to characters that are used to divide or structure text, and these are classified into different types based on their roles. Unicode assigns these punctuation characters specific categories.

Whitespace

Whitespace is a commonly used concept for a typographic effect. Basically it covers invisible characters that have a spacing effect in rendered text. It includes spaces, tabs, and new line formatting controls. In Unicode, such a character has the property set WSpace=yes. In version 17.0, there are 25 whitespace characters.

Casing

The Case value is normative in Unicode. It pertains to those scripts with uppercase and lowercase letters. Case-difference occurs in Adlam, Armenian, Beria Erfe, Cherokee, Coptic, Cyrillic, Deseret, Garay, Glagolitic, Greek, Khutsuri and Mkhedruli Georgian, Latin, Medefaidrin, Old Hungarian, Osage, Vithkuqi and Warang Citi scripts.

Different languages have different case mapping rules.

In Turkish, U+0069 i LATIN SMALL LETTER I corresponds to U+0130 İ LATIN CAPITAL LETTER I WITH DOT ABOVE instead of U+0049 I LATIN CAPITAL LETTER I. Similarly, U+0049 I LATIN CAPITAL LETTER I when corresponds to U+0131 ı LATIN SMALL LETTER DOTLESS I instead of U+0069 i LATIN SMALL LETTER I.

In Nawdm, the letter Ĥ corresponds to ɦ in lowercase instead of the usual case mappings being Ĥĥ and Ɦɦ.

In Greek, the letter sigma has different lowercase forms depending on where it is in a word. U+03A3 Σ GREEK CAPITAL LETTER SIGMA converts to U+03C3 σ GREEK SMALL LETTER SIGMA if it is at the start or middle of a word, and converts to U+03C2 ς GREEK SMALL LETTER FINAL SIGMA if it is at the end of a word.

In Lithuanian, the dot in lowercase i and j is preserved when followed by accents. For example: Í in lowercase is i̇́.^[19]

Despite the existence of U+1E9E ẞ LATIN CAPITAL LETTER SHARP S, U+00DF ß LATIN SMALL LETTER SHARP S corresponds to "SS".

Unicode encodes 31 titlecase characters.

Other general characteristics

Unicode defines several general character properties in the Unicode Character Database (UAX #44). Some of the most important ones include:

Ideographic — Characters that represent ideas or concepts rather than specific sounds. These include most Han (CJK) characters used in Chinese, Japanese, and Korean writing systems.^[20]

Alphabetic — Characters that are considered letters in an alphabetic or syllabic writing system. This includes Latin, Greek, Cyrillic letters, as well as characters from syllabaries like Hiragana.^[21]

Noncharacter — Code points that are permanently reserved for internal use and are not assigned to any abstract character. These include U+FDD0 through U+FDEF, and any code ending in FFFE or FFFF (such as U+1FFFE, U+10FFFF).^[22]

Combining class

Some common codes:

0 = spacing letter, symbol or modifier (e.g. a, (, ʰ)

1 = overlay

6 = Han reading (CJK diacritic reading marks)

7 = nukta (diacritic nukta in Brahmic scripts)

8 = kana voicing marks

9 = virama

10–199 = various fixed-position classes

Marks which attach to the base letter:

200 = attached at bottom left

202 = attached directly below (e.g. cedilla on ç)

204 = attached at bottom right

208 = attached to left

210 = attached to right

212 = attached to top left

214 = attached directly above

216 = attached at top right

Marks which do not attach to the base letter:

218 = bottom left

220 = directly below (e.g. ring on n̥)

222 = below right

224 = left

226 = right

228 = above left

230 = above (e.g. acute accent on á)

232 = above right

233 = double below (subtends two bases)

234 = double above (extends two bases)

240 = iota subscript (only that Greek diacritic)

Bidirectional writing

Six character properties pertain to bi-directional writing: Bidi_Class, Bidi_Control, Bidi_Mirrored, Bidi_Mirroring_Glyph, Bidi_Paired_Bracket and Bidi_Paired_Bracket_Type.

One of Unicode's major features is support of bi-directional (Bidi) text display right-to-left (R-to-L) and left-to-right (L-to-R). The Unicode Bidirectional Algorithm UAX9^[23] describes the process of presenting text with altering script directions. For example, it enables a Hebrew quote in an English text. The Bidi_Character_Type marks a character's behaviour in directional writing. To override a direction, Unicode has defined special formatting control characters (Bidi-Control characters). These characters can enforce a direction, and by definition only affect bi-directional writing.

Each code point has a property called Bidi_Class. It defines its behaviour in a bidirectional text as interpreted by the algorithm:

Bidirectional character type (Bidi_Class Unicode character property)^[1]

Notes 1.^ Unicode Bidirectional Algorithm (UAX#9), As of Unicode version 16.0 2.^ Possible Bidirectional character types for character property: Bidi_Class or 'type' 3.^ Bidi_Control characters: Twelve Bidi_Control formatting characters are defined. They are invisible, and have no effect apart from directionality. Nine of them have a unique, overruling BiDi-type that is used by the algorithm. Their type is also their acronym (e.g. character 'LRE' has BiDi type 'LRE').

In normal situations, the algorithm can determine the direction of a text by this character property. To control more complex Bidi situations, e.g. when an English text has a Hebrew quote, extra options are added to Unicode. 12 characters have the property Bidi_Control=Yes: ALM, FSI, LRE, LRI, LRM, LRO, PDF, PDI, RLE, RLI, RLM and RLO as named in the table. These are invisible formatting control characters, only used by the algorithm and with no effect outside of bidirectional formatting.^[23] Despite the name, they are formatting characters, not control characters, and have General category Other, format (Cf) in the Unicode definition.

Basically, the algorithm determines a sequence of characters with the same strong direction type (R-to-L or L-to-R), taking in account an overruling by the special Bidi-controls. Number strings (Weak types) are assigned a direction according to their strong environment, as are Neutral characters. Finally, the characters are displayed per a string's direction.

Two character properties are relevant to determining a mirror image of a glyph in bidirectional text: Bidi_Mirrored=Yes indicates that the glyph should be mirrored when written R-to-L. The property Bidi_Mirroring_Glyph=U+hhhh can then point to the mirrored character. For example, parentheses (, ) are mirrored this way. Shaping cursive scripts such as Arabic, and mirroring glyphs that have a direction, is not part of the algorithm.

Numeric values and types

Decimal

Characters are classified with a Numeric type.^[1] Characters such as fractions, subscripts, superscripts, Roman numerals, currency numerators, encircled numbers, and script-specific digits are type Numeric. They have a numeric value that can be decimal, including zero and negatives, or a vulgar fraction. If there is not such a value, as with most of the characters, the numeric type is "None".

The characters that do have a numeric value are separated in three groups: Decimal (De), Digit (Di) and Numeric (Nu, i.e. all other). "Decimal" means the character is a straight decimal digit. Only characters that are part of a contiguous encoded range 0..9 have numeric type Decimal. Other digits, like superscripts, have numeric type Digit. All numeric characters like fractions and Roman numerals end up with the type "Numeric". The intended effect is that a simple parser can use these decimal numeric values, without being distracted by say a numeric superscript or a fraction. Eighty-three CJK Ideographs that represent a number, including those used for accounting, are typed Numeric.

On the other hand, characters that could have a numeric value as a second meaning are still marked Numeric type None, and have no numeric value. E.g. Latin letters can be used in paragraph numbering like "II.A.1.b", but the letters "I", "A" and "b" are not numeric (type None) and have no numeric value.

Hexadecimal digits

Hexadecimal characters are those in the series with hexadecimal values 0123456789ABCDEF (sixteen characters, decimal value 0–15). The character property Hex_Digit is set to Yes when a character is in such a series:

Characters in Unicode marked `Hex_Digit=Yes`^[a]
`0123456789ABCDEF`	Basic Latin, capitals	Also `ASCII_Hex_Digit=Yes`
`0123456789abcdef`	Basic Latin, small letters	Also `ASCII_Hex_Digit=Yes`
`０１２３４５６７８９ＡＢＣＤＥＦ`	Fullwidth forms, capitals
`０１２３４５６７８９ａｂｃｄｅｆ`	Fullwidth forms, small letters
a. ^ "Unicode 17.0 UCD: PropList.txt". 2025-06-30. Retrieved 2025-09-11.

Forty-four characters are marked as Hex_Digit. The ones in the Basic Latin block are also marked as ASCII_Hex_Digit.

Unicode has no separate characters for hexadecimal values. A consequence is, that when using regular characters it is not possible to determine whether hexadecimal value is intended, or even whether a value is intended at all. That should be determined at a higher level, e.g. by prepending 0x to a hexadecimal number or by context. The only feature is that Unicode can note that a sequence can or can not be a hexadecimal value.

Block

A block is a uniquely named, contiguous range of code points. It is identified by its first and last code point. Blocks do not overlap, nor do they extend across planes. The number of code points in each block must be a multiple of 16. A block may contain code points that are reserved, not-assigned, etc. Each character that is assigned, has a single "block name" value from the 346 names assigned as of Unicode version 17.0. Unassigned code points outside of an existing block have the default value "No_block".

Script

Each assigned character can have a single value for its "Script" property, signifying to which script it belongs.^[24] The value is a four-letter code in the range Aaaa-Zzzz, as available in ISO 15924, which is mapped to a writing system. Apart from when describing the background and usage of a script, Unicode does not use a connection between a script and languages that use that script. So "Hebrew" refers to the Hebrew script, not to the Hebrew language.

The special code Zyyy for "Common" allows a single value for a character that is used in multiple scripts. The code Zinh "Inherited script", used for combining characters and certain other special-purpose code points, indicates that a character "inherits" its script identity from the character with which it is combined. (Unicode formerly used the private code Qaai for this purpose.) The code Zzzz "Unknown" is used for all characters that do not belong to a script (i.e. the default value), such as symbols and formatting characters. Overall, characters of a single script can be scattered over multiple blocks, like Latin characters. And the other way around too: multiple scripts can be present is a single block, e.g. block Letterlike Symbols contains characters from the Latin, Greek and Common scripts.

When the Script is "" (blank), according to Unicode the character does not belong to a script. This pertains to symbols, because the existing ISO script codes "Zmth" (Mathematical notation), "Zsym" (Symbol), and "Zsye" (Symbol, emoji variant) are not used in Unicode. The "Script" property is also blank for code points that are not a typographic character like controls, substitutes, and private use code points.

If there is a specific script alias name in ISO 15924, it is used in the character name: U+0041 A LATIN CAPITAL LETTER A, and U+05D0 א HEBREW LETTER ALEF.

Normalization properties

Decompositions, decomposition type, canonical combining class, composition exclusions, and more.

Age

Age is the version of the standard in which the code point was first designated. The version number is shortened to the numbering major.minor', although there more detailed version numbers are used: versions 4.0.0 and 4.0.1 both are named 4.0 as Age. Given the releases, Age can be from the range: 1.1, 2.0, 2.1, 3.0, 3.1, 3.2, 4.0, 4.1, 5.0, 5.1, 5.2, 6.0, 6.1, 6.2, 6.3, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0, 12.1, 13.0, 14.0, 15.0, 15.1, 16.0 and 17.0.^[25] The long values for Age begin in a V and use an underscore instead of a dot: V1_1, for example.^[2] Codepoints without a specifically assigned age value have the value "NA", with the long form "Unassigned".

Deprecated

Once a character has been defined, it will not be removed or reassigned.^[26] However, a character may be deprecated, meaning its "use is strongly discouraged".^[27] As of Unicode version 17.0, the following fifteen characters are deprecated:^[28]

Alias name

Unicode can assign alias names to code points. These names are unique over all names (including regular ones), so they can be used as identifier. There are five possible reasons to add an alias:

1. Abbreviation: Commonly occurring abbreviations or acronyms for control codes, format characters, spaces, and variation selectors.; For example, U+00A0 NO-BREAK SPACE has alias NBSP. Sometimes presented in a box:
NBSP
.
2. Control: ISO 6429 names for C0 and C1 control functions and similar commonly occurring names, are added as an alias to the character.; For example, U+0008 <control-0008> has the alias BACKSPACE.
3. Correction: This is a correction for a "serious problem" in the primary character name, usually an error.; For example, U+2118 ℘ SCRIPT CAPITAL P is actually a lowercase p, and so is given alias name WEIERSTRASS ELLIPTIC FUNCTION: "actually this has the form of a lowercase calligraphic p, despite its name, and through the alias the correct spelling is added." In descriptions, with preceding symbol ※.
4. Alternate: A widely used alternate name for a character.; Example: U+FEFF ZERO WIDTH NO-BREAK SPACE has the alternate alias BYTE ORDER MARK.
5. Figment: Several documented labels for C1 control code points which were never actually approved in any standard (figment meaning "feigned, in fiction").; For example, U+0099 <control-0099> has the figment alias SINGLE GRAPHIC CHARACTER INTRODUCER. This name is an architectural concept from early drafts of ISO/IEC 10646-1, but it was never approved or standardized.
