Proper UNICODE support would have to go beyond wchar_t substitution. Recognizing compound characters ( like O and umlaut in sequence ) and upper/lower case issues ( in some scripts there is no clear mapping ) would appear to be a non-trivial modification to Lua. On our game we basically use wide characters as 16bit index into a glyph array and I assume that's what Verant wants to do too. I agree that an easy way to set the character size is a good idea but full UNICODE support is a mine field.

Take care,
Guy English

ps. Built in co-routines would make me really, really happy.
