You did not mention: Have you already filed a bugreport against
potlatch2? I think it was not intended to push this key.
I mentioned it to RichardF, but have been following up on the
replication side first.
Have you checked whether we have more unintended tagging like this in
the database?
We've encountered about 50 other occurrences of duplicate keys which are
likely caused by this bug. I have no estimate on how many keys in the
database have control characters without conflicting with another tag.
Taginfo has a report about potentially problematic characters, but it
does not seem to consider control characters.

The OSMF taginfo instance uses the replication diffs, so is impacted by
the osmosis bug like any other diff consumer.
For next steps, I'll write this up for the osmosis issue tracker.
