    {
        $cleanText = "";

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

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

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