> I'd be *very* suspicious of any application that tried to disable the normal system font management [ I'm assuming that by "the normal system font management" you mean FontConfig's fallback mechanism. ] I believe I have good reasons to do so. I want my app to have its own fallback mechanism. This fallback mechanism will not just replace one font with another, as FontConfig seems to be doing, but do the fallback on a grapheme cluster granularity. (My app does its own layout, parsing GSUB and GPOS and other OT tables.) For this, I need to be able to tell whether a particular font is present on the system or not. > I'd say look up gucharmap's code gucharmap doesn't seem to use FontConfig (I grepped for "Fc" and got no matches), but maybe it uses another facility e.g. Pango, which relies on FC. So it doesn't really answer my question about whether I can get FontConfig to tell me whether a particular font is present on the system or not. Thanks for your response!
