If you are missing fonts that you where able to use before in the offline creator tool for Windows, you can follow the steps below to make them visible again.

1. Go to the "Help & Options" tab.
2. Click on "Settings".
3. Uncheck the checkbox "Show only TrueType fonts for text editing".

Please note: if you have a lot of fonts installed, unchecking this box can make the editor respond slower than usual.
