fonttools not setting usMaxContext when compiling fea

[bobh0303]

The FEA compiler should be responsible for setting the OS2.usMaxContext value, but it seems to be coming out 0.

/smith/font-harmattan/results$ ttfdump -t OS/2 Harmattan-Regular.ttf | grep Context
         usMaxContext:           0

That field is extremely bogus. That said, yes, we can add code to calculate it.

your script is using ufo2ft, which should calculate that field automatically

https://github.com/googlei18n/ufo2ft/blob/master/Lib/ufo2ft/maxContextCalc.py

if not, could you file an issue over there with more info? Thanks

The issue was incorrectly stated. We're not utilizing ufo2ft to compile OpenType, but rather fonttools. I'll correct the title of this issue.

So the issue is same as fonttools/fonttools#466
