cmap subtables format

[Asmaa]

Hello Everybody,
I'm developing an OpenType font Library, that extracts the font metric i.e. font information of a given font file.
Now I am supposed to cover all the cmap subtables formats ([0, 2, 4, 6] and [8, 10, 14])

- I couldn't find a font file that contains any font file with cmap 8, 10 or 12
- Also, the only cmap table for the windows platform (platformID=3) in all the fonts that I found is cmap 4, so I find difficulty testing my
  developed Library.

Please Advise,

Thanks a lot for your help in advance,

Best Regards,
Asmaa
