While looking at the font props in the Acrobat Pro 2020 I get this weird behavior where for few fonts the name is "Family,Style" instead of "Family-style". The same happens when we read this value via the SDK
Its not isolated to Calibiri but for other fonts as well
Its also reporducible across different machines
Any insights/link to known issues is highly appreciated
Doesn't sound weird. Some fonts are like that, and some PDF generators do that. You can't assume the internal names will match any particular pattern, rule, or repository.
I check the fonts in the font tools we use, and the name was read correctly
The fonts were used directly into the pdf and not added during document import/conversion
It's normal. Expect and handle the case.
So basically, I will be replacing "," with a "-" yes?
And have you seen such similar data inconsistencies
No. As you were told, you can't predict what the internal font name will be based on the display name, or anything else. You have to get that name from the font itself.
