How can I change extended latin characters to their unaccented ASCII equivalents?

Question

I need a generic transliteration or substitution regex that will map extended latin characters to similar looking ASCII characters, and all other extended characters to \'\'

Answer 1

Maybe a CPAN module might be of help?

Text::Unidecode looks promising, though it does not strip ‡ or Ω or ‰. Rather these are replaced by ++, O and %o. This might or might not be what you want.

Text::Unaccent, is another candidate but only for the part of getting rid of the accents.
