I have found some information on Wikipedia concerned with XeTeX and the unicode-math package. My question is, if I include the unicode-math package in my document, is it enough to have LaTeX installed and run the Unix latex command on my file, or do I need to have XeLaTeX installed as well in order to transform my source file into a .dvi/.ps/.pdf file?

    Don't you have xetex and/or luatex installed with your TeX distribution already? Commented Feb 7, 2015 at 16:41

    Yes, you need to use XeLaTeX or LuaLaTeX and so you will only get PDF. You most probably have both XeTeX and LuaTeX installed already, so just execute xelatex file.tex or lualatex file.tex.

  • Well, I haven't typeset LaTeX in quite a long time, and last time I was using tetex (by Thomas Esser) which no longer exists, and this did not come with XeTeX or LuaTex. What should I install on Linux, and what should I install on Windows to have these available (given that tetex doesn't support them)? Thanks. Commented Feb 7, 2015 at 16:49
  • Also, isn't LUA a scripting language to facilitate OpenGL game programmers to write code? What does LUA have to do with LaTeX? I've read the Wikipedia article on luatex but things are still not clear to me. Thanks. Commented Feb 7, 2015 at 16:50

    There's MikTeX for Windows, and TeXLive for every platform.

You can't run documents using unicode-math with the legacy latex. The only possibility is with XeLaTeX or LuaLaTeX, that are included in any recent TeX distribution.
