NAME
       fmt_utf8 - encode 31-bit unsigned integer using UTF-8 rules

SYNTAX
       #include <fmt.h>

       size_t fmt_utf8(char *dest,uint32_t source);

DESCRIPTION
       fmt_utf8 encodes a 31-bit unsigned integer using the UTF-8 rules.  This
       can take from 1 byte (0-0x7f) up	 to  5	bytes  (0x4000000-0x7fffffff).
       Values larger than 0x7fffffff cannot be represented in this encoding.

       If  dest	 equals FMT_LEN (i.e. is NULL), fmt_utf8 returns the number of
       bytes it would have written.

       For convenience, fmt.h defines the integer FMT_UTF8 to be big enough to
       contain every possible fmt_utf8 output.
