Hello, I developped a Japanese dictionnary in XeTeX.
It compiles just fine in luatex but I would like to code the commands in
Lua instead of TeX.
To make the code faster, cleaner, simpler and more powerfull.
Yet, I need to be able to manipulate utf-8 strings (find, substring,
replace, length, etc...).
Is there a simple way to do that in LUA ? Will there be one day a luatex
library for utf8 string managments ?
(because it seems the string library is just for strings with 1 byte
characters and it is really lacking)
Keep up the good work.
