function highlight($string, $term_to_search, Transliterator $tlr) {
    $normalizedStr = $tlr->transliterate($string);
    $normalizedTerm = $tlr->transliterate($term_to_search);

    $termPos = mb_strpos($normalizedStr, $normalizedTerm);
    // Actually, `mb_` prefix is useless since strings are normalized

    if ($termPos === false) { //term not found
        return $string;
    }

    $termLength = mb_strlen($term_to_search);
    $termEndPos = $termPos + $termLength;
    
    return
        mb_substr($string, 0, $termPos)
        . '<b>' // this is the highlight code
        . mb_substr($string, $termPos, $termLength)
        . '</b>' // this is the end of the highlight code
        . mb_substr($string, $termEndPos);
}

$tlr = Transliterator::create('Any-Latin; Latin-ASCII; Lower();');

echo highlight('Would you like a café, Mister Kàpêk?', 'kape', $tlr);
// Result: Would you like a café, Mister <b>Kàpêk</b>?
