al_utf8_encode
size_t al_utf8_encode(char s[], int32_t c)
Encode the specified code point to UTF-8 into the buffer s. The buffer must have enough space to hold the encoding, which takes between 1 and 4 bytes. This routine will refuse to encode code points above 0x10FFFF.
Returns the number of bytes written, which is the same as that returned by al_utf8_width.
