| Converts UTF-8 string `s` to a local multi-byte character string.
const char * | fl_utf8_next_composed_char (const char *from, const char *end)

const char * | fl_utf8_previous_composed_char (const char *from, const char *begin)
| Returns pointer to beginning of character before given location in UTF8 string accounting for emoji sequences.
const char * | fl_utf8back (const char *p, const char *start, const char *end)
| Move `p` backward until it points to the start of a UTF-8 character.
int | fl_utf8bytes (unsigned ucs)
| Return the number of bytes needed to encode the given UCS4 character in UTF-8.
unsigned | fl_utf8decode (const char *p, const char *end, int *len)
| Decode a single UTF-8 encoded character starting at p.
int | fl_utf8encode (unsigned ucs, char *buf)

| Convert an ISO-8859-1 (ie normal c-string) byte stream to UTF-8.
unsigned | fl_utf8fromwc (char *dst, unsigned dstlen, const wchar_t *src, unsigned srclen)
| Turn "wide characters" as returned by some system calls (especially on Windows) into UTF-8.
const char * | fl_utf8fwd (const char *p, const char *start, const char *end)
| Move `p` forward until it points to the start of a UTF-8 character.
int | fl_utf8len (char c)
| Returns the byte length of the UTF-8 sequence with first byte `c`, or -1 if `c` is not valid.
int | fl_utf8len1 (char c)
| Returns the byte length of the UTF-8 sequence with first byte `c`, or 1 if `c` is not valid.
int | fl_utf8locale ()
| Return true if the "locale" seems to indicate that UTF-8 encoding is used.
int | fl_utf8strlen (const char *text, int len)
| Return the length in bytes of a UTF-8 string.
