While this is indeed true, and often annoying for people who use non latin
character sets, a good part of the strings that Lua uses are program code,
which is usually made up of latin characters.
This fact is fuzzied by the fact that Lua can accept identifiers using non
ASCII characters, depending on the locale in use. Still, the proportion of
latin characters is likely to be high enough for the space gain to be a
I agree that string intensive programs will diminish this ratio though, if
using non latin characters.

>From what I've read on the list, one of the key advantages of Lua over other
languages is its small size. Indiscriminate use of wchar_t for all strings
would be a waste of space. I don't deny the fact that wchar_t has
but I thought I would underline this.
