utf8_getc_limit

Get the next UTF-8 gchar at ptr, and return it, advancing ptr to the next character.

If end is reached before a full UTF-8 character can be read, then the invalid Unicode gchar 0xffff is returned as a sentinel ( Unicode 3.1, section 2.7), and ptr is not advanced.

Parameters:

ptr	a pointer to read the character from
end	upper limit for the read, must not be null

Returns:

The next UTF-8 char, or 0xffff.
