Do you possibly consider to allow value/variable names encoded UTF8 in lua?
This for sure would be VERY nice for very many users in Asia...
You can try to use LuaJIT (formally speaking, it's a fork of Lua 5.1).
It does allow using arbitrary Unicode symbols in a variable name.
For example, you can make valid (but invisible!) variable name consisting of non-breaking space (U+00A0).
But developers from other countries may have difficulties reading and modifying your code containing non-English letters.
