If ToASCII succeeds, the original sequence and the resulting sequence are equivalent labels. It is important to note that the ToASCII operation can fail. ToASCII fails if any step of it fails. If any step of the ToASCII operation fails on any label in a domain name, that domain name MUST NOT be used as an internationalized domain name. The method for dealing with this failure is application\-specific. The inputs to ToASCII are a sequence of code points. ToASCII never alters a sequence of code points that are all in the ASCII range to begin with (although it could fail). Applying the ToASCII operation multiple effect as applying it just once. When unsure, it is recommended to call this function with the \fBIDN2_NONTRANSITIONAL\fP and \fBIDN2_NFC_INPUT\fP flags. Return value: Returns \fBIDN2_OK\fP on success, or error code. .SH "SINCE" 2.0.0 .SH "SEE ALSO" The full documentation for .B libidn2 is maintained as a Texinfo manual. If the .B info and .B libidn2 programs are properly installed at your site, the command .IP .B info libidn2 .PP should give you access to the complete manual.
