A few observations, reading this page:

Lack of "\U+1234" style unicode character escapes - it strikes me  
that the code to isolate such an escape, and then convert it to an 8  
bit string would only take a few lines of code. Is there a good  
theological reason why this isn't supported?

Inability to use UTF-8 identifiers due to use of isalpha and isalnum  
- surely it would be better to use  hardcoded functions for  
determining if the characters in an identifier are valid? Otherwise  
there will be potential locale issues anyway. Locales should apply to  
human languages, not computer languages!

Unicode string comparison and normalisation issues - I might be being  
forgetful, but I was under the impression C99 added Unicode compliant  
wide character comparison functions - perhaps these should be used if  
present?
