InDesign Package Fonts issue
File > Package (including the fonts) seems to work fine on Mac
I have no problem opening the indd file in the package folder on a PC/windows even though if I try to open the fonts packages in the Document Fonts folder it shows two of the TrueType Fonts collection files are invalid. This is confusing??
When others download the Indesign Package folder from Google drive (which includes the Document Fonts folder), it gives an error "missing fonts" when opening the wsame indd file I opened fine on Mac & PC above.
As far as I know, we are all using the latest version of InDesign
The missing fonts are the invalid TrueType Fonts collection Didot & helvetica seen in the screenshot below. I can't find these online to download or I would go this route
