       The final output string is not within the (inclusive) range 1 to 63
       characters.

IDNA_NO_ACE_PREFIX
       The string does not contain the ACE prefix (for ToUnicode).

IDNA_ROUNDTRIP_VERIFY_ERROR
       The ToASCII operation on output string does not equal the input.

       containing a description of the error with the return code  rc .
