- updated to version 0.9.3:
* Bug fixes in unistr.h functions:
- The functions u16_to_u32, u16_to_u8, u8_to_u32, u8_to_u16 now fail when
the argument is not valid. Previously, they returned a converted string
where invalid parts were each replaced with U+FFFD.
- The function u8_mbsnlen now counts an incomplete character at the end
of the argument string as 1 character. Previously, it could count as 2
or 3 characters.
- The return value of the u8_stpncpy, u16_stpncpy, u32_stpncpy functions
was incorrect.
- The u8_strcoll, u16_strcoll, u32_strcoll now try harder to give a non-zero
return value.
