[HarfBuzz] List of languages supported by harfbuzz

[Samiullah Khawaja]

Thanks, your help is really appreciated.

I have some more questions... how can i find direction of the text? Is HB
able to determine the text direction by itself?

I have a text that is a mixture of Arabic and English words i.e. a mixture
of RTL and LTR text. How can I use harfbazz to process that?

Best Regards,
Sami
