I just installed Libreoffice 6.3 in Linux Mint 18, 64bit, KDE. I would like to remove all non-English fonts, such as Alef and Amiri. The system font manager does not see these fonts, and therefore I cannot remove them this way.
I now know that LO has it’s own private collection under /opt/libreoffice6.3/share/fonts/truetype/
I tried renaming the fonts by changing the extension: Alef-Bold.ttf → Alef-Bold.ttf.bak. However this did not work and LO still shows the Alef font.
It would be very nice if there was an option at the UI to manage these fonts, and allow the user to either add or remove specific fonts at will.
Your help will be appreciated.
