As indicated in
https://github.com/googlefonts/Inconsolata/issues/42#issuecomment-573409054,
the information returned by font-info for this font on Fedora is:

  ["-CYRE-Inconsolata-normal-normal-normal-*-19-*-*-*-m-0-iso10646-1" "Inconsolata:pixelsize=19:foundry=CYRE:weight=normal:slant=normal:width=normal:spacing=100:scalable=true" 19 21 0 0 0 29 17 4 29 29 "/usr/share/fonts/levien-inconsolata/Inconsolata-Regular.ttf" (opentype ((DFLT ...) (latn ... ... ... ... ... ... ... ... ...)) (DFLT (nil mark mkmk)) (latn (nil mark mkmk) (AZE\ mark mkmk) (CAT\ mark mkmk) (CRT\ mark mkmk) (KAZ\ mark mkmk) (MOL\ mark mkmk) (ROM\ mark mkmk) (TAT\ mark mkmk) (TRK\ mark mkmk)))]

and I think the "scalable=true" part is the problem.  AFAIK, it isn't
supposed to be there, since the average width is reported as non-zero
for this font.  But that's just a wild guess.  I guess it comes from
Fontconfig.

Sadly, I have no idea how to go about investigating this problem
further, maybe someone else does?

FWIW, this problem doesn't happen on MS-Windows with the same font.
