Because you have fix the slug type back to string, the old support for CJK characters won't work again. So I fix it.

By the way, the new DISQUS comment system is very good.

I will test this and merge it later tonight, thanks!

You can test with a title like

• 测试中文
• This is 中文
• 私は日本語

And you can see the example in my blog. It works in yin8086/simple@7eb533daa75ec7ebaa675bf798dfffb5be62df5c with Chinese translation.

Thanks for this, it all appears to work correctly. I haven't merged this directly but I have added your changes.
