I think it's best to encode DNA strings as sequences of ubyte. UTF 
routines will work slower on them than functions for ubyte.

I think the names are fine. It doesn't take much learning to understand 
that char, wchar, and dchar are UTF-8, UTF-16, and UTF-32 code units 
respectively. I mean it would be odd if they were something else.
