SYNOPSIS

       #include <idn2.h>

       int idn2_to_unicode_4z4z(const uint32_t * input, uint32_t ** output, int flags);

ARGUMENTS

DESCRIPTION

       Converts  a  possibly  ACE  encoded  domain  name  in  UTF-32  format into a UTF-32 string
       (punycode decoding). The output buffer will be zero-terminated and must be deallocated  by
