As the world gets smaller each day, internationalization becomes more and more important.   For handling multiple languages, Unicode is your best friend.

It is a very capable tool, but also quite complex compared to older single- and double-byte character encodings.

How well prepared is your programming language for Unicode?



Task

Discuss and demonstrate its unicode awareness and capabilities.



Some suggested topics:

   How easy is it to present Unicode strings in source code? 
   Can Unicode literals be written directly, or be part of identifiers/keywords/etc?
   How well can the language communicate with the rest of the world? 
   Is it good at input/output with Unicode?
   Is it convenient to manipulate Unicode strings in the language?
   How broad/deep does the language support Unicode? 
   What encodings (e.g. UTF-8, UTF-16, etc) can be used? 
   Does it support normalization?


Note

This task is a bit unusual in that it encourages general discussion rather than clever coding.
