Why are only some custom fonts being applied on Windows10?

Problem with custom fonts in Windows10

Hi Team,

I am trying to use the custom fonts, tried applying to TextBlock, some fonts are getting applied and some are not.

Not sure whether this is due to the font file (.ttf). This same problem i observed even with windows phone 8.x and windows 8.1 also.

Thanks,
Pramod.
