XeTeX
XeTeX (/ˈziːtɛx/ ZEE-tekh or /ˈziːtɛk/; see also Pronouncing and writing "TeX"), sometimes stylized as XeTeX, is a TeX typesetting engine using Unicode and supporting modern font technologies such as OpenType, Graphite and Apple Advanced Typography (AAT). It was originally written by Jonathan Kew and is distributed under the X11 free software license.
Initially developed for Mac OS X only, it is now available for all major platforms. It natively supports Unicode and the input file is assumed to be in UTF-8 encoding by default. XeTeX can use any fonts installed in the operating system without configuring TeX font metrics, and can make direct use of advanced typographic features of OpenType, AAT and Graphite technologies such as alternative glyphs and swashes, optional or historic ligatures, and variable font weights. Support for OpenType local typographic conventions (locl tag) is also present. XeTeX even allows raw OpenType feature tags to be passed to the font. Microtypography is also supported. XeTeX also supports typesetting mathematics using Unicode fonts that contain special mathematical features, such as Cambria Math or Asana Math as an alternative to the traditional mathematical typesetting based on TeX font metrics.
LaTeX developers have announced that they no longer support new LaTeX functionalities on the XeTeX engine, and encourage users to migrate to LuaTeX, another Unicode-supporting engine.
XeTeX processes input in two stages. In the first stage XeTeX outputs an extended DVI (xdv) file, which is then converted to PDF by a driver. In the default operating mode the xdv output is piped directly to the driver without producing any user-visible intermediate files. It is possible to run just the first stage of XeTeX and save the xdv, although as of July 2008[update] there are no viewers capable of displaying the intermediate format.
Two backend drivers are available to generate PDF from an xdv file:
Starting from version 0.997, the default driver is xdvipdfmx on all platforms. As of version 0.9999, xdv2pdf is no longer supported and its development has been discontinued.
XeTeX works well with both LaTeX and ConTeXt macro packages. It is usually invoked through xelatex when using LaTeX. It is usually used with the fontspec package, which provides a configurable interface for font selection, and allows complex font choices to be named and later reused.
XeTeX is bundled with TeX Live, MacTeX, MiKTeX and Lyx (see the History below for dates and versions).
