The wiki points to <http://luaforge.net/projects/sln/>. Peter has it in the LuaDist gist but I don't know if he's accepting patches. <https://github.com/LuaDist/slnunicode>. I've been doing pretty well with the pure Lua UTF-8.lua library but haven't fully exercised it. You might give it a try. <http://www.curse.com/addons/wow/utf8>. The wiki mentions some other resources that I haven't tried near the bottom of this page. <http://lua-users.org/wiki/LuaUnicode>. Best regards, Paul
