function custom_text_validation_filter( $result, $tag ) {
    if ( \'your-name\' == $tag->name ) {
        // matches any utf words with the first not starting with a number
        $re = \'/^[^\\p{N}][\\p{L}]*/i\';

        if (!preg_match($re, $_POST[\'your-name\'], $matches)) {
            $result->invalidate($tag, "This is not a valid name!" );
        }
    }

    return $result;
}
