At some point, the system font Arial was spontaneously replaced. In my font library I have some old old version of Arial font, which doesn’t even have Cyrillic alphabet. And at some point FontBase substituted system Arial for this old version, and browsers stopped displaying Cyrillic. I could not understand what happened until I saw where the system Arial refers to in the Windows Control Panel through the font management tool. It turned out that its path was substituted FontBase on the old archive version. And until I removed this font completely from the folder, the system did not want to see the system Arial. Although in the Windows/Fonts folder there was the correct latest version of the font from Microsoft.
Hello again @clusterx, thank you for your post
Indeed such situations are possible if activating system fonts via FontBase. This is why it is highly recommended not to add the system font folder and system fonts into FontBase to avoid similar issues.
Should probably add a note on this in the official FAQ section as this topic has been discussed on this forum several times already.
No, I didn’t add the system font folder to FontBase. I wrote that I had a very old Arial font in the archive (it’s just a folder with a bunch of fonts on an external hdd). And FontBase activated it instead of normal system Arial. It was very strange.
Thank you for the clarification
To avoid similar situations, it would be best not to add fonts into FontBase if they are already permanently active (e.g. installed) in your system, as happened with Arial.
