note 113925 added to function.iconv

A function to convert UTF-8 to best-fit ASCII. Handles punctuation too. Characters it doesn't understand get converted to '?'. <?php function utf8_to_ascii($text) { if (is_string($text)) { // Includes combinations of characters that present as a single glyph $text = preg_replace_callback('/\X/u', __FUNCTION__, $text); } elseif (is_array($text) && count($text) == 1 && is_string($text[0])) { // IGNORE characters that can't be TRANSLITerated to ASCII $text = iconv("UTF-8", "ASCII//IGNORE//TRANSLIT", $text[0]); // The documentation says that iconv() returns false on failure but it returns '' if ($text === '' || !is_string($text)) { $text = '?'; } elseif (preg_match('/\w/', $text)) { // If the text contains any letters... $text = preg_replace('/\W+/', '', $text); // ...then remove all non-letters } } else { // $text was not a string $text = ''; } return $text; } $text = 'Française señor café 0123 කොහොමද ශ්‍රී ලංකා hello Žluťoučký kůň ' .
