The way I understand it is that std.uni is (supposed to be) for 
functions on individual unicode units (be they code units/points 
or graphemes) and std.utf is for functions which handle operating 
on unicode strings. Obviously there are exceptions. I think 
"they" put graphemeStride in std.uni because Grapheme was defined 
there and it seemed reasonable at the time. But, generally I 
think utf stuff should go into std.utf.
