PDF can't show chinese

Hello~
When I use process() to export pdf，I can't show chinese in my pdf file.
Is there exist any way to setting export language or i have to include chinese font name?
Thanks u~

Hello @acer22969 Please check supported locales:
http://www.oracle.com/technetwork/java/javase/java8locales-2095355.html and then configure this way:

$options = [
    'format' => ['pdf'],
    'locale' => 'zh-CN',
    'params' => [],
    'db_connection' => [
        'driver' => 'postgres', //mysql, ....
        'username' => 'DB_USERNAME',
        'password' => 'DB_PASSWORD',
        'host' => 'DB_HOST',
        'database' => 'DB_DATABASE',
        'port' => '5432'
    ]
];

Thank for you answer
But I will get a error like :
Undefined offset: 0
If I set 'locale' => '' to 'locale' => 'zh-TW'

I fix the last question
But I got new error like:

I fix the problem too.
It's must be 'locale' => 'zh_TW' not 'locale' => 'zh-TW'
But even I doesn't get any error,I still can't show chinese in my pdf file.QQ
