Semantics is everything. For me graphemes are the endpoint (or should be); to 
get a proper rendering of a sequence of graphemes I can use either a sequence of 
bytes or a sequence of codepoints. They are both encodings of the graphemes; 
what unicode says is an encoding doesn't define what encodings are ie mappings 
from some source alphabet to a target alphabet.
