           Summary: Improve size unparse?
        QA Contact: freedesktop at behdad.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: freedesktop at behdad.org
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: library
           Product: fontconfig

Try eg:

$ fc-query /usr/share/fonts/opentype/cantarell/Cantarell-Regular.otf --format
'%{=unparse}'

Used to print:

Cantarell:familylang=en:style=Regular:stylelang=en:fullname=Cantarell
Regular:fullnamelang=en:slant=0:weight=80:width=100:foundry=unknown:index=0:outline=True:scalable=True:charset=

Now prints:

Cantarell-(0

Regular:fullnamelang=en:slant=0:weight=80:width=100:foundry=unknown:file=/usr/share/fonts/opentype/cantarell/Cantarell-Regular.otf:index=0:outline=True:scalable=True:charset=

The 1.79769e+308 is really ugly.  Not sure what to do.  Perhaps support
printing 'inf' or something?  Also in other places.
