It is encoded in the Latin Extended-D block, which belongs to the Basic Multilingual Plane. It was added to Unicode in version 12.0 (March, 2019). It is HTML encoded as Ꞻ. xterm #344 is a little earlier than that. Its fallback copy of wcwidth doesn't list that range (I updated the table to Unicode 12 in #345, and added a test-driver around that time). The system wcwidth doesn't cover that range either.

I'm guessing that it was #327 (it should not have worked, but there's always the possibility that I fixed a bug which was making it appear to work) -- Thomas E.
