If the fonts do not display correctly, look garbled or change to another font while editing, this might be because the font is not supported by the system and thus by our app. Here's what you can try:
- Go to Edit mode in PDF Expert, click on the affected text and check the name of the font at the right panel.
- Download the font with this name.
- After you've downloaded it, please add it to Font Book app on your Mac (it's s standard system app).
- Once it's added, please restart PDF Expert and check if the same issue persists in this file.
Right now, we do not support third-party fonts, but there's a possible workaround - you can install the custom fonts to iFont app. Here's the tutorial you can use.
