Linux File Names converted to blank rect after running sudo fc-cache -f -v

I'm beginner in Linux.

I have downloaded some fonts from net and I made some mistake to rebuild Ubuntu by these fonts. So I copied them to .fonts folder in home directory. After that I run this command and all files and folders names are converted to blank rects as showed in bellow:

sudo fc-cache -f -v

How could I repair Ubuntu? Currently I have these fonts in mentioned folder and I could not remove them:

rm: cannot remove '/home/ai-station/.fonts/Ubuntu-MI.ttf': Permission denied
rm: cannot remove '/home/ai-station/.fonts/Ubuntu-B.ttf': Permission denied
rm: cannot remove '/home/ai-station/.fonts/Ubuntu-L.ttf': Permission denied
rm: cannot remove '/home/ai-station/.fonts/Ubuntu-BI.ttf': Permission denied

If you don't have permissions to the folder, use sudo to elevate your permissions and give you access to the directory where you get permission denied errors.

If the [font] files were added in a home directory; I'd just remove them.

Please note I'd not try and do it in the difficult-to-read gui, instead logout [of gui] and but switch to terminal (ctrl+alt+F4 etc), re-run fc-cache (rebuild font info cache index), then re-login into gui. I would expect gui to look normal at this login :)

Please note Ubuntu 18.10 is now EOL & off-topic on this site because of EOL status. You should release-upgrade to 19.04 ASAP
