How to find out which alphabets support a true type font

[Heidi Kurz]

Hi together, 

I need some help about the following problem. 

I use the Shaper module to render unicode letters like Arabic or Hephrew. 

Now I need a functionality how to find out which alphabets support a true type font. 

For example I have to render Arabic strings, but not all available true type fonts support Arabic letters. So I have to choose the correct available true type font. 

I hope you can understand my problem. 

BR, Heidi

There is somewhat simple support for this in Skia with
SkFontMgr::matchFamilyStyleCharacter. Note that this is what
FontMgrRunIterator::consume currently uses to do font fallback.

Different platforms handle font fallback and matching in different
ways ways, though recently it may be possible to provide a bit better
implementation in Skia which could be supported cross platform. The
main issue here is that it is fairly time consuming to go through a
collection of fonts and extract the character map information, so
every platform tries to cache this information as much as possible.
