Module:Diacritics

-- convertChar returns the non-diacritic version of the supplied character. stripDiacrits replaces words with diacritical characters with their non-diacritic equivalent. strip_diacrits is available for export to other modules. isLike tests two words, returning true if they only differ in diacritics, false otherwise. is_like is available for export to other modules. --
