How can I merge two (CID-Keyed) fonts using AFDKO mergefonts (or anything else)

Hello everyone!

I'm looking for almost the same answers as asked in this topic, just a little late after it was posted, but I'm having the almost exact same issue.

I'm trying to merge two CID-keyed fonts using AFDKO mergefonts command. One of them is a converted name-keyed to CID-keyed, following Dr. Ken Lunde steps, producting a working .otf file that I can open an type with in every software.

After the mergefonts operation, I do get OTF file, with a filesize equal to the sum of the other two, I can't open it in either Glyphs, FontTableViewer nor Fontdrop; saying it Doesn't have a Name Table. The two fonts are separately openable in different softwares, with both a readable Name / CFF table.

If there is some AFDKO hero in here, I would love to have some advice input, even if that means using anything else than AFDKO !

(I've read Adobe docs & tips as much as I can and have been following the steps and advices as precisely as I could, I feel like I'm almost there, but I'm missing something I can't put the finger on).

Thanks a lot in advance!
