[HarfBuzz] Which Non-Latin Scripts Do Free Software Fonts Not Cover?

[Dave Crossland]

Hi All,

I've just started the Masters degree in Typeface Design at the
University of Reading (for which Gentium was a submitted project) and
we're expected to do a non-latin script complement to our font, and
I'd thought I'd ask around if anyone here has any opinions about the
following:

Are there non-latin scripts that free software fonts do not cover at
all at the moment?

Which non-latin script communities are adopting free software and
would benefit from more fonts?

Does Harfbuzz have problems with setting any scripts in particular?
Are some scripts supported better than others?

:-)
