Description:
stringprep profile for Internationalized Domain Names (RFC 3491)
Net::IDN::Nameprep implements the nameprep specification, which describes how to prepare internationalized domain name (IDN) labels in order to increase the likelihood that name input and name comparison work in ways that make sense for typical users throughout the world. Nameprep is a profile of the stringprep protocol and is used as part of a suite of on-the-wire protocols for internationalizing the Domain Name System (DNS).
