UTF-8 issues

[Eldar Insafutdinov]

I faced some issues with utf-8 support in D.
As it stated in http://www.digitalmars.com/d/2.0/cppstrings.html strings support slicing and length-calculation. Since strings are char arrays this is correct only for latin strings. So when the strings for example cyrillic chars - length is wrong, indexing also doesn't work, and slicing too.
But foreach works correctly. So utf-8 support is partial. Maybe there are functions from standart library that does this work? I checked D2 new features - there was not improving utf-8 support - am I wrong?
