BookStack is great. But recently I noticed that it does not support Unicode character.

Like when a page title is fully written in other language other then English. Means there is no English character all written in Unicode character, Page URL is not created.

Also PDF generates ambiguous character when document is written in Unicode character.

I am running PHP 7.0 with Mysql 5.5.49

Will you please provide support for Unicode? It very very much import for global user.

I see you're using Mysql 5.5.x, does it exhibit the same behavior on Mysql 5.6?

BookStack requires Mysql 5.6 as shown here: https://www.bookstackapp.com/docs/admin/installation

Also what version of BookStack is this?

Hi @xianx, Since you have not responded to the above from nwalke I will close this issue. If you are still having issues with this and answer the above questions I'll happily re-open this.

Hello here, i have this problem too.
I start bookstack from docker images (offical)
Mysql 5.7.12
Bookstack version 0.18.4
@ssddanbrown, I ask you to take a look at this problem again.
My article was written in Russian, with an extort I got it.
When exporting to html, the output is correct

Relatedly, PDF export clobbers scientific pages since a lot of mathematical unicode symbols don't seem to work:

This is with Bookstack 0.27.4. Expected output is μL instead of ?L
