I've been thinking about UTF-8 and Lua lately, and wonder how much work it would be to actually support that in Lua "out of the box". There are some programming languages (s.a. Tck) that claim already to do that, and I feel the concept would match Lua's targets and philosophy rather nicely.

I understand UTF-8 might not be everyone's favourite, but it is mine. :) And having a working framework (str:bytes(), str:length(), str:width()) could easily be adopted to other extended encoding schemes as well.

The reason I'm bringing this up right now, is that the issue could suit nicely with the 5.1 "every type has a metatable" way of thinking; would it warrant an opportunity to have a closer look at what Lua means by 'strings' (or rather, their encoding) anyhow?
