 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).
