Hi Paolo,

I really have no idea.  We're just reading in the raw bytes from the  
source file, so I guess it depends on whatever the source encoding  
is.  In practice, this sounds like a really bad idea :).

Clang doesn't have any notion of an input character set at present,  
and doesn't handle unicode escapes.  How do other compilers handle  
input character sets?  Are there command line options to specify it?   
Should the AST hold the string in a canonical form like UTF8?
