>> https://github.com/fontforge/fontforge/blob/master/fontforge/othersubrs.c This code seems to be based on https://github.com/adobe-type-tools/afdko/tree/master/FDK/Tools/Programs/public/lib/source/t1write/t1write_flexothers.* and now Adobe Font Development Kit for OpenType (AFDKO) is licensed under Apache-2.0 license. Fontforge is licensed under GPL-3, so it's not a problem to embedded it. Thanks, Read and other folks in Adobe :) Bug#665334 "non-DFSG postscript embedded in fontforge" is solved. However, I don't know it is okay for other pfb files with license conflicts. Apache-2.0 conflicts with GPL-2, at least, and it may conflict with other license, too. Just "type 1 fonts include Adobe all right reserved code" is not a problem, but if those type 1 fonts would be licensed under certain license like GPL-2 that conflict with Apache-2.0...? And, how can I think about fontforge copies snippet to generate those *.pfb files? It's for Bug#694308.
