Configure PDF Language

https://support.atlassian.com/browse/CSP-53406

We have tried your suggestion of uploading a ttf file. Problem is, bold, italic are not rendered anymore inside the PDF.

I have even tried to create a ttc file from 4 ttfs (regular,bold,italic,bolditalic) with the Microsoft tool makettc, but Confluence will only consider the regular subset.

So, how should we do to upload a font which will render the different type of characters (greek, ....) and type of style (bold, italic, ...)

Thx
