module to remove diacritics from a string

 Text::Undiacritic provides a module that changes characters with diacritics
 into their base characters.
 .
 Also changes into base character in cases where UNICODE does not provide a
 decomposition.
 .
 E.g. all characters '... WITH STROKE' like 'LATIN SMALL LETTER L WITH STROKE'
 do not have a decomposition. In the latter case the result will be 'LATIN
 SMALL LETTER L'.
 .
 Removing diacritics is useful for matching text independent of spelling
 variants.
