idn2_to_ascii_lz - API function
int idn2_to_ascii_lz(const char * input, char ** output, int flags);
const char * input
zero terminated input UTF-8 string.
char ** output
pointer to newly allocated output string.
int flags optional idn2_flags to modify behaviour.
Convert a domain name in locale's encoding to ASCII string using the
IDNA2008 rules. The domain name may contain several labels, separated
by dots. The output buffer must be deallocated by the caller.
The default behavior of this function (when flags are zero) is to apply
the IDNA2008 rules without the TR46 amendments. As the TR46
non-transitional processing is nowadays ubiquitous, when unsure, it is
recommended to call this function with the IDN2_NONTRANSITIONAL and the
IDN2_NFC_INPUT flags for compatibility with other software.
IDN2_OK on success, or error code. Same as described in
