Thank you for the reply.  Very helpful.

For Inconsolata-VariableFont_wdth,wght.ttf, I was able to call
FcPatternGetRange on the FcPattern that is causing trouble, and I
confirmed that the weights of all the other FcPatterns from the file
fall within the beginning and end of that range.

However, if I call FcPatternGetBool on the pattern for the FC_VARIABLE
property, I get FcResultNoMatch -- what does that mean?

Thanks again.
