Character set coverage information

[chrissimpkins]

Include information on character set coverage for each font. Separate gallery markdown file with examples from broad range of character sets? Icons next to font names?

Suggestions welcomed

from @van-de-bugger in #119 :

Did you try fontimage program from fontforge package? It does not use fallback fonts. It is not suitable for syntax highlighters, but may be suitable for Text Specimen and Compact Text Specimen.

$ fontimage --text "Жы" --text "Ψω" --text "です" --o sample.png ./Hack-Regular.ttf

I suppose Hack does not have Japanese glyphs?

Just FYI:

fc-query (from fontconfig package) may be used to get information about font coverage, e. g:

$ fc-query /usr/share/fonts/google-roboto/Roboto-Regular.ttf

Look at charset and lang. However, I have no idea how to represent it in a compact and understandable form. Charmap is too long; list of languages is shorter but still too long.

I would say that at least percentage completion in a chart like this could be pretty useful:
