Right now the only example I have is Junicode version 0.6.11 from
<URL:http://junicode.sf.net/>. If I open Junicode-Regular.sfd I see a
feature list starting with 'rtla', 'smcp', 'c2sc', 'liga' ....
Generating a TTF from this I get a feature list starting with ' RQD',
'c2sc', 'ccmp', .... This is the same ordering of features as present in
the TTFs available at the above site.

I have tried to build a smaller example but haven't succeeded yet.

BTW, Junicode-Regular.sfd contains:

TableOrder: GPOS 0
TableOrder: GSUB 0

Might this be related? How is feature order decided in such a case?
