The correct solution is a well implemented, well updated and well 
debugged Unicode Collation Algorithm, as already answered.
But if an approximation is enough then you could translate to D 
this Python code that converts a Unicode string to ASCII, and use 
it through a  schwartzSort:

(If you translate that function to D, you could also add it to 
Dub later.)
