I suggested a way forward for these iconv warnings that will be new in
2.34.0 at [1], poked'd a few days ago at [2].

Jeff: What do you think? Per [1] I think it's best to drop it entirely
for now, or split out just the "completely unknown encoding" problem
from "can't decode this particular thing".

You also had a patch in [3] that wasn't picked up, which would warn
about this once.

If we *are* going to warn that seems like the worst of both in some
sense, i.e. we'll no longer give users anything like "in this huge
commit stream, we couldn't search in commit XYZ", instead we just warn
on whatever happens to be the first commit, and you'll have no idea if
subsequent matches were completed or not.
