使用 Google Calendar API (PHP) 插入包含非 ASCII 字符的事件

I'm using the following code to create the event:

function buildGoogleEvent($title,$description,$start_time,$end_time,$location) {
    // Create an event object and set some basic event information
    $event = new Google_Event();
    $event->setSummary($title);
    $event->setLocation($location);
    $event->setDescription(htmlentities($description, ENT_NOQUOTES, 'utf-8'));

    // Convert the start and end date/times to ATOM format
    $start_time_atom = str_replace(" ", "T", $start_time);
    $end_time_atom = str_replace(" ", "T", $end_time);

    // Add the event start to the event object
    $start = new Google_EventDateTime();
    $start->setDateTime($start_time_atom);
    $start->setTimeZone('Europe/London');
    $event->setStart($start);

    // Add the event end to the event object
    $end = new Google_EventDateTime();
    $end->setDateTime($end_time_atom);
    $end->setTimeZone('Europe/London');
    $event->setEnd($end);

    return $event;
}

这段代码插入了事件:

$createdEvent = $service->events->insert($google_calendar_id, $event);

已经坐了很长一段时间，因此感谢您的帮助！我的 PHP 版本是 5.5.4.

$event->setDescription(utf8_encode($description));
