Jonathan Kew XeTeX Live With the release of TeX Live 2007, XeTeX has "come of age" and entered the mainstream of the TeX world. The XeTeX engine, which provides built-in Unicode and OpenType support, is now a standard part of a TeX Live installation, and thus is readily available to any user who installs this distribution. This presentation will show how users can take advantage of XeTeX to easily use additional fonts in TeX or LaTeX documents, with no complex installation or setup procedures. It will also show how non- Latin scripts such as Chinese, Arabic, Devanagari, and many others can be typeset just as easily as English, thanks to full Unicode support throughout the system. In addition, some of the newest developments in XeTeX (beyond the TeX) Live 2007 release) will be discussed and demonstrated. These include support for the Graphite rendering technology for complex scripts; extensions that can simplify Chinese/Japanese character spacing and mixed-script typesetting; and more complete Unicode math support.
