@deftypefun {int} {gnutls_idna_reverse_map} (const char * @var{input}, unsigned @var{ilen}, gnutls_datum_t * @var{out}, unsigned @var{flags})
@var{input}: contain the ACE (IDNA) formatted domain name

@var{ilen}: the length of the provided string

@var{out}: the result in an null-terminated allocated UTF-8 string

@var{flags}: should be zero

This function will convert an ACE (ASCII-encoded) domain name to a UTF-8 domain name.

If GnuTLS is compiled without IDNA support, then this function
will return @code{GNUTLS_E_UNIMPLEMENTED_FEATURE} .

Note also, that this function will return an empty string if an
empty string is provided as input.

@strong{Returns:} A negative error code on error, or 0 on success.

@strong{Since:} 3.5.8
