Not at this moment. as you may know the rendering libraries has a trick to do that these days. e.g. they know what clusters of characters has a script and querying a font with the different pattern including the language which is most likely. Well, it can be improved if fontconfig supports that right. in fact I have an idea to do that with the language tag though, it isn't a short-term plan so far. > 2) To be able to switch off automatic font substitutions entirely, > either system-wide or per-application. > > Due to automatic substitutions, character picker utilities are unable > to indicate whether a font has the glyph for a particular character or > not.

That sounds like not a fault of fontconfig. how it behaves depends on rendering libraries or applications. fontconfig just gives an idea of the better font against the request. if they simply do follow that and it doesn't contain the certain glyphs say, it won't be renderred properly like applications without using fontconfig open a font directly. Speaking of pango, you can stop that fallback with pango_attr_fallback_new(FALSE). > > So I'd like to know how to achieve the above two requirements.
