Fonts are available all over the internet. There are paid fonts available, and free fonts. Usually the free fonts can cause some problems in the editor since the files are not of a high enough quality. So when you’re experiencing issues with a free font, this could be the cause of that.

The Google fonts from https://fonts.google.com/ will most likely be accepted by the editor and won’t cause any problems.
