       illegal by RFC 3629, such as 0xffff, are considered legal by this.
     - Returns 1 if there are only single-byte characters (ie no bytes
       have the high bit set). This is legal UTF-8, but also indicates
-      plain ASCII. It also returns 1 if \a srclen is zero.

     - Returns 3 if there are only characters less than 0x10000.
