[datatable-help] Merging strings claim that the encodings don't match

[caneff at gmail.com]

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
