Hi,
Open question concerning Calibre and FONTS.

I want to remove from Calibre-[preferences]-[common options]-[fonts]-[embed font family] a list of "font families".
In this case it is different versions of Charis Sil that I have used in the past.

I have just one version, which I am using, that I have selected but all the old/other versions are still showing as options.
I have manually deleted the fonts folder in Calibre config folder and recreated with ONLY the Charis Sil family I am using.
I watched it create a new .json file in that folder.

I know it doesn't effect anything but I just want to have a tidy install as it took me about 40 hours of work to find a Charis Sil font that works with the latest firmware and the patches with [fullpagereading] set to TRUE and NOT have the issue with lines at top and bottom margin going past the page.
Anyone with a Kobo Glo will know what I am talking about above.

But my question is for Calibre - how do I just show 1 Charis Sil Font in list of [embed font family]?

Thanks and I hope someone has an easy answer.
BTW, I do not know how to code in python so I hope it is not a coding issue.

Thank you for your time.

My apologies if this is in the wrong forum. I searched and this seemed the only place where fonts were being discussed.
