function trim_characters( $text, $length = 340 ) {

$length = (int) $length;
$text = trim( strip_tags( $text ) );

if ( strlen( $text ) > $length ) {
    $text = substr( $text, 0, $length + 1 );
    $words = preg_split( "/[\s]| /", $text, -1, PREG_SPLIT_NO_EMPTY );
    preg_match( "/[\s]| /", $text, $lastchar, 0, $length );
    if ( empty( $lastchar ) )
        array_pop( $words );

    $text = implode( ' ', $words ); 
}

return $text;

}
