What would you think of an iterator based approach with the following 
interface:

   // Bideirectional iterator for UTF8 / UTF16 coded data
   // I: Raw data iterator
   // C: Unicode character type
   template <class I, typename C> class unicode_iterator;

   // I: Unicode character iterator
   template <typename I> class unicode_string;

   // some standard types:
   typedef unicode_iterator<std::string::iterator, wchar_t> utf8_iterator;
   typedef unicode_iterator<std::basic_string<short>::iterator, wchar_t> 
utf16_iterator;
   typedef std::wstring::iterator utf32_iterator;

   typedef unicode_string<utf8_iterator> > utf8_string;
   typedef unicode_string<utf16_iterator> > utf16_string;
   typedef unicode_string<utf32_iterator> > utf32_string;

This would allow a lot of algorithms to work directly together whith a 
"slim" unicode framework.
