    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";
    }
    }
    ?>

    Outputs:
