Hi,
I'd like to add support for dealing with utf-8 text in Lua 5.1 - for functions such as string.gsub, string.len and etc. I'm aware 5.3 comes with a utf8 library but I'm not considering breaking capability for the huge ecosystem of code that's been developed for 5.1 for my application just yet.
I know there's starwing/luautf8, are there any other options that I should be considering?
