@zyx,
Thank you for your query. Unfortunately, I don’t understand the issue. You are checking embedded fonts, and when the fonts exist, you are logging the fonts are not found. Could you describe more details about the problem, please?

I want IWarningCallback to work, but he doesn’t seem to print anything, but in fact he should print out some fonts and can’t find it
