Fonts in Package not installing on Windows

[geoffry]

This may have been addressed, but I could not find it:

I am working alternately on Mac and Windows. A package I created on the Mac with a MacOS font (Kitari) does not install the font in Windows, so it is very hard to edit it without being able to judge the effects on the font.

Any suggestions?

Kitari is a collection of eight OTF fonts in one file - Kitari.ttc.

Apple has a habit of purposely breaking the TTC files so they do not install on Windows.
So to extract the font files you need an application which will ignore the bad checksums and extract the fonts.
I used FoundryTools-CLI to extract this TTC.
https://github.com/ftCLI/FoundryTools-CLI
FontCreator (FC) and FontLab (FL) will also open these broken TTC files.

Usually the fonts inside the TTC also have bad checksums - and have to be fixed.
Fixed as in a round-trip thru fonttools ttx, or an open-and-save from FC or FL.
FoundryTools-CLI also has a roundtrip thru ttx command.
But these fonts are OK and will install in Windows (which is unusual).
And they are standard OpenType (not Apple AAT fonts which will not work properly).

Thanks for this! Will try them out later... really appreciate the help, and the tip with FoundryTools.
