I have a master DT. I aggregate it in one way, and aggregate it in another with a common key between them. When I try to merge these two, it says that the key does not have the same encoding on both sides. If I call Encoding() on each of the keys, they both are listed as "unknown", so from what I can see they still look the same.
I can't create a safe to share reproducible case unfortunately, the simple ones I've tried all work. If you can give more advice on how to debug maybe I can. This is using the latest devel version. I did not have this issue i 1.8.10
