Ugh. Right make sense.

Seems okay I guess. We should probably query the terminal and make
sure it's in utf8 mode before assuming utf8.
Although, it's not clear to me what we would do if it's not in utf8
mode, and you seem to handle non-utf8 about as well as could be
expected, so maybe not worth bothering.
Anyway, looks okay to me. As you probably guessed, I don't like the names :-)
I would prefer maybe
ply_utf8_string_get_length ()
and
ply_utf8_character_get_size ()
since size normally means "in bytes" and length normally means "in
other units" (with the oddball exception of strlen which returns a
size instead of a length)
