public PhpTransliteration::removeDiacritics($string)
Removes diacritics (accents) from certain letters.
This only applies to certain letters: Accented Latin characters like a-with-acute-accent, in the UTF-8 character range of 0xE0 to 0xE6 and 01CD to 024F. Replacements that would result in the string changing length are excluded, as well as characters that are not accented US-ASCII letters.
Parameters
string $string: The string holding diacritics.
Return value
string $string with accented letters replaced by their unaccented equivalents.
