How can I find out which fonts on my system include coverage of a certain character, for example, U+2192?
I've tried looking in Character Map, but I don't see a way to query fonts by character, only characters by font.
For installed fonts which have the Unicode character U+2192, you could use fc-list:
fc-list :charset=2192
Example output:
/usr/local/share/fonts/consolas/consolab.ttf: Consolas:style=Bold
/usr/local/share/fonts/consolas/consolai.ttf: Consolas:style=Italic
/usr/local/share/fonts/consolas/consola.ttf: Consolas:style=Regular
/usr/local/share/fonts/consolas/consolaz.ttf: Consolas:style=Bold Italic
/usr/share/fonts/opentype/cantarell/Cantarell-Bold.otf: Cantarell:style=Bold
/usr/share/fonts/opentype/cantarell/Cantarell-ExtraBold.otf: Cantarell,Cantarell Extra Bold:style=Extra Bold,Regular
...
/usr/share/texmf/fonts/opentype/public/lm/lmsansquot8-oblique.otf: Latin Modern Sans Quotation,LM Sans Quot 8:style=8 Oblique,Bold Italic
/usr/share/texmf/fonts/opentype/public/lm/lmsansquot8-regular.otf: Latin Modern Sans Quotation,LM Sans Quot 8:style=8 Regular,Regular
/usr/share/texmf/fonts/opentype/public/lm-math/latinmodern-math.otf: Latin Modern Math:style=Regular
For formatting the output, there is also a poorly documented -f format option. See man FcPatternFormat and the fontconfig documentation page which has a list of some available properties.
For example:
fc-list -f "%{file}
%{family}
" :charset=2192
