By default, Content Exporter only supports a subset of fonts. If you want to export documents which contain fonts not supported by Content Exporter, need to register additional fonts.
To upload a custom font:
- Go to General Configuration → Content Exporter → PDF Custom fonts
- Enter a name for the font. (This name will be visible in the font selector on the profile editor)
- Select font files to upload
- Click Upload
You can find some fonts at:
