The Text::Iconv module provides a Perl interface to the iconv() function as
defined by the Single UNIX Specification.

The convert() method converts the encoding of characters in the input string
from the fromcode codeset to the tocode codeset, and returns the result.

Settings of fromcode and tocode and their permitted combinations are
implementation-dependent. Valid values are specified in the system
documentation; the iconv(1) utility should also provide a -l option that lists
all supported codesets.
