IMHO, obviously the number of bytes. You can have additional O(N) 
numCodePoints() and (if needed) utf16Size() (which takes needed surrogate 
pairs into account) methods, but the inherent size is the number of bytes.

IMHO, a byte index, and if that chops the codepoint, so be it, same as for 
the surrogate pairs in the UTF-16 QString. Anything else is just not doable 
with reasonable efficiency.
