Does anyone know why MacOs prefers to use the name id's 16 and 17 for the Windows platform over the id's 16 and 17 for Macintosh the platform? Adobe InDesign on Mac also uses the id's for Windows.

    Shouldn't they be the same?
    16 and 17 namerecords are for Windows usage
    18 = 4, if 18 is empty, + FOND data for Mac

    That is because those Windows platform fields are stored with UTF-16BE encoding, thus support Unicode text. The Macintosh platform uses legacy encodings.

    Yes, but I made an otf with both id's 16 and 17 for Macintosh and Windows platform and gave them different names to be able to identify which entry is used.

    Okay thanks! So in what cases would make sense then to have id's 16 and 17 for the Macintosh platform?
