How do we handle unicode (utf-8) codepages?

[Shachar Shemesh]

What do we do if the user requests a Unicode codepage? I've just had a 
conversation with a user on IRC where I believe things didn't work for 
him because LANG was set to es_ES.UTF-8. On one hand, I don't think we 
can force ANSI applications to work in Unicode. On the other hand, we 
cannot change the locale - it will mean noone (whether ANSI or not) will 
not be able to access non-ASCII file names and files.

Comments?
