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 ![image](https://user-images.githubusercontent.com/12625945/31957416-23076412-b908-11e7-9ade-054e92b9fabd.png) ![image](https://user-images.githubusercontent.com/12625945/31957529-836fdbfe-b908-11e7-9f7e-a7cd9b5c1630.png)

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

PDF export titles can lose non-ASCII characters due to heading font fallback in DOMPDF. I added a PDF-only heading font override to DejaVu Sans and verified Polish titles export correctly. This should help other languages too; PR landed -> https://github.com/BookStackApp/BookStack/pull/6069.

Within #6109 I've created system for loading custom fonts to use in (default DOMPdf based) PDF exports.
There will be documentation to show how custom fonts can be loaded using this system, where a language may not be supported by default for these PDF exports.
This will be part of the next feature release.

@alexwoo-awso I think that was related, but a bit different to the fundamental issues here, which is that the default font support (and default styles) don't cover the full range of languages/characters folks may need. --- Within #6109 I've created system for loading custom fonts to use in (default DOMPdf based) PDF exports.
