Font goes missing on a new computer

Hello all,

Is there a repository of fonts online?

I have a new computer, and I noticed that one font I used is missing.

Another thing: I don't know the missing name of the missing font. I am going to insert an image from a PDF version of the drawing. I would appreciate it if you can identify it.

Thanks!

I don't think that this is a font contained in LibreCAD.
All LibreCAD bundled fonts are here: https://github.com/LibreCAD/LibreCAD/tree/master/librecad/support/fonts
