Internationalizing Domain Names in Applications (IDNA)
Net::IDN::Encode provides an easy-to-use interface to encode and decode Internationalized Domain Names (IDNs). . IDNs use characters drawn from a large repertoire (Unicode), but IDNA allows the non-ASCII characters to be represented using only the ASCII characters already allowed in so-called host names today (letter-digit-hypen, /[A-Z0-9-]/i).
