Issue Description

It seems Acrobat Reader is unable to properly render the information in the table on p.831 of 981 of the Ubuntu Server documentation found at https://ubuntu.com/server/docs/_/downloads/en/latest/pdf/ :

I am trying to read this on a PC with Win11, Acrobat Reader Version 2026.001.21483 (latest version as of 28 April 2026, no further updates available).

Maybe using something plain like “Y”, “N”, “O”, “X”, or whatever makes most sense, rather than exotic symbols would be better?

I can confirm, just by opening the PDF on Firefox, that the utf-8 characters are not rendered correctly. We'll look into this.

After digging further into this, it seems that there are problems in general with missing characters into the Ubuntu mono font pack. I have reported this to the web team so we can get these added.
