UTF-16 to UTF-32 and backward is quite trivial and can 
be done in 10-20 rows of code. You can borrow some 
code from Boost.Locale it is really trivial.

If you need I'll give you samples.

Really, don't add dependency for this...

I can tell you char16_t and char32_t are far-far-far-far from
being useful especially if you want to use codecvt or something
like that.

  
http://cppcms.sourceforge.net/boost_locale/html/status_of_cpp0x_characters_support.html

So don't be in hurry to implement anything useful for them, currently
these characters support is totally broken with major compilers.
