I understand what you are saying. However, everyone should move towards
using break iterator, I believe, for performance reasons!
 
I could add more options to the extract call to allow the user to specify
what $start means:

GRAPHEME_EXTR_START_BYTE_COUNT
GRAPHEME_EXTR_START_CHAR_COUNT
GRAPHEME_EXTR_START_GRAPHEME_COUNT
 
The next question would be - what is the default? Should it be 'byte count'
in all cases, or should it match the $extract_type - graphemes if 'count',
bytes if 'max bytes' etc. I suspect the latter, if I understand your
use-case.

Thoughts?
