Does (should?) fontTools enforce "valueCount must == Coverage glyphCount" for SinglePosFormat2?
See original GitHub issuePer OTSpec in SinglePosFormat2 subtables, the valueCount “must equal glyphCount in the Coverage table.” The attached ttx dump uses a SinglePosFormat2 with Coverage glyphCount of 2 and no ValueRecords (i.e. count = 0). ttx compiles this with the format2 subtable’s valueCount set to zero and a non-empty Coverage (count = 2), with no error or warning issued. Is this expected?

Yes, this is the kind of things that OTS does I believe.
I’ll poke around there and see what’s going on. The current version doesn’t seem to flag it.
I’ll close this out as there’s no action needed here.
