This is wrong: most codepoints in the range U+0080-U+07ff (the ones
greater than U+0400) would be interpreted as being 1 character long
instead of 2.
Thanks for the heads-up. Maybe a more reliable solution would be to call
mbtowc(3) repeatedly as new input arrives until it returns successfully.
Assuming the first read byte is a UTF-8 start byte.
Not needed. Only case 0xD0 is missing.
case 0xC0: case 0xD0:
return 2;
