@ssddanbrown commented on GitHub (Dec 5, 2023):
Looking into this, the upstream library we use for PDF generation does not support RTL content.
We do allow WKHTML as another PDF renderer, but that requires sacrificing security, and that project is no longer supported, while it still has issues with RTL from my testing (At least with current BookStack code).
We'd probably need to look to a new optional render at some point (for this and various other issues).
Note: As an alternative for pages you can often use the browser's print-to-pdf option to get a good representative result where desired.
