Font Upload Failed Missing the required OS/2 table

[Papaotter]

One of my users is getting the above error, Font Upload Failed - Missing the required OS/2 table, when they try to load an .indd file. The fonts contained within the indd file are all fonts that are already installed and available on her machine. Does anyone know how to remedy this error?

Fonts are not contained within an InDesign document but certainly are referenced by an InDesign document.

The OS/2 table referenced by the error message refers to a required component of either TrueType, OpenType CFF, or OpenType TrueType fonts. It contains critically-important information about the font required to properly format, display, and print text using that font. You can find specifications for the OS/2 table at https://docs.microsoft.com/en-us/typography/opentype/spec/os2.

Quite frankly, I have never heard of a situation where InDesign (actually, the underlying font engine of same) yielded such a diagnostic of “missing the required OS/2 table.” It would be very hard to imagine either Windows or MacOS allowing installtion of such a damaged font.

My only advice would be to uninstall the font in question completely from the system, reboot the system, and then reinstall the font from a known working copy.

Let us know if that resolves the problem (and also perhaps, exactly what font was causing this problem).
