Hi. Of áâãäåæçèéêëìÃ*îïðñóôõö÷øù the only ones that should be in the $phpdig_words_chars['iso-8859-7'] variable are æçðø like so:
PHP Code:
$phpdig_words_chars['iso-8859-7'] = '[:alnum:]æçðø';
These áâãäåèéêëìÃ*îïñóôõö÷ù are accented/diacritic characters and need to be matched up to their Latin counterparts in $phpdig_string_subst['iso-8859-7'].
