=== Testing for UTF-8-aware TeX ===
 
 
<i>(By [[User:Taco|Taco]]); this hint should be place to a better location on the wiki</i>
 
 
For luatex, one may test if <code>\directlua</code> is defined.
 
 
The next weird macro definition should work for testing xetex/luatex, because only xetex and luatex accept 5- and 6-byte caret notation (hex 22 == double quote):
 
<texcode>
 
\def\"{0}\expandafter\def\csname^^^^^00022\endcsname{1}
 
\ifnum\"=0 \message{tex82}\else\message{newstuff}\fi
 
</texcode>
 
 
But that is not quite the same as testing for native UTF-8. Better is a trick like this:
 
 
<texcode>
 
\def\test#1#2!{\def\secondarg{#2}}
 
\test χ!\relax % That's Chi, a 2-byte utf-8 sequence
 
\ifx\secondarg\empty \message{newstuff}\else \message{tex82}\fi
 
</texcode>
 
 
ConTeXt offers <code>\beginNEWTEX ... \endNEWTEX</code> to test if one is using LuaTeX or XeTeX.

LuaTeX is an extended version of PdfTeX using Lua, as an embedded scripting language. The LuaTeX project's main objective is to provide an open and configurable variant of TeX while at the same time offering downward compatibility.

The project started in the summer of 2005, and has since progressed into a first official early beta that was released during the TUG2007 conference in San Diego. Development is supported by a grant from Colorado State University and the TeX User groups.

The official website offers some more information.
