An example of using this to find all the code points in a string that cannot be transliterated to Latin-ASCII:



<?php



$string = "Народm, Intl gurus get paid €10000/hr 😁";



$latinAscii = Transliterator::create('NFC; Any-Latin; Latin-ASCII;');

$transliterated = $latinAscii->transliterate($string);



$codePoints = IntlBreakIterator::createCodePointInstance();

$codePoints->setText($transliterated);



foreach ($codePoints->getPartsIterator() as $char) {

    $ord = IntlChar::ord($char);

    if (255 < $ord) {

        echo IntlChar::charName($ord) . "\n";

    }

}

?>
