perl-text-unaccent (perl module to remove accents from a string)

Text::Unaccent is a module that remove accents from a string.

unac_string converts the input string from the specified charset
to UTF-16 and calls unac_string_utf16 to return the unaccented
equivalent. The conversion from and to UTF-16 is done with iconv(1).

See also: system/unac, for a library and command-line tool that does
the same thing.
