    $clean_text = "";

    // Match Emoticons
    $regexEmoticons = '/[\x{1F600}-\x{1F64F}]/u';
    $clean_text = preg_replace($regexEmoticons, '', $text);

    // Match Miscellaneous Symbols and Pictographs
    $regexSymbols = '/[\x{1F300}-\x{1F5FF}]/u';
    $clean_text = preg_replace($regexSymbols, '', $clean_text);

    // Match Transport And Map Symbols
    $regexTransport = '/[\x{1F680}-\x{1F6FF}]/u';
    $clean_text = preg_replace($regexTransport, '', $clean_text);

    // Match Miscellaneous Symbols
    $regexMisc = '/[\x{2600}-\x{26FF}]/u';
    $clean_text = preg_replace($regexMisc, '', $clean_text);

    // Match Dingbats
    $regexDingbats = '/[\x{2700}-\x{27BF}]/u';
    $clean_text = preg_replace($regexDingbats, '', $clean_text);

    return $clean_text;
