[I am not on list, so please cc me.] I want to use Texinfo for a program that uses UTF-8 @code, including math styles, and as such, the solution to that does not matter. Cf. sample [1]. Perhaps it requires some further development:
I have tried LuaTeX with an OTF font, which requires additional code from ConTeXt: the files luaotfload.sty and luatex-math.tex. The latter file must be tweaked for the font used; I have tried the STIX font, but other choices might be Pagella or Termes. One problem is that 'info' generation does not accept user defined commands like @stixfonts, nor is it possible to use @tex as it creates an environment. Another problem is to get letters with diacritics right: some part translates them back to traditional TeX commands, which then is written out verbatim. Also, the tweak overrides the @code monospace. 1. https://secure2.storegate.com/Shares/Home.aspx?ShareID=c18543d2-639f-478f-b15a-44a4c2a9b519
