Thanks for raising @wzhz. I believe this is essentially due to the same thing as issue #719 so I'll close this.

In short: it's tricky for us to support all font options for the default PDF rendering system in an efficient manner. BookStack does support an alternative PDF rendering system (WKHTMLtoPDF) which can be trickier to set-up (Especially in docker environments) but has much better UTF8 support & and more accurate page rendering.

感谢您提出@wzhz。我认为这本质上是与问题＃719相同的缘故，因此我将关闭它。

简而言之：对于我们而言，要有效地支持默认PDF呈现系统的所有字体选项是很棘手的。BookStack确实支持替代的PDF呈现系统（WKHTMLtoPDF），该系统设置起来比较麻烦（尤其是在docker环境中），但具有更好的UTF8支持和更准确的页面呈现。

Thank you very much for your reply

I also encountered the same problem, using English can export pdf perfectly, but using Chinese seems to be unable to render, I am using the latest version 0.31.6 Ubuntu 20.04
