Select the text inside the illustrator and character panel is empty, never show any fonts be using. My computer didn't install the fonts but can display correctly in illustrator.
When exported to PDF, can check the fonts is using Lora-Bold.

I'm really frustrated and worries, how to check incoming files if always having this issue.

Please help on this method.

Version: Adobe illustrator 2022 and 2023
