Marking this as 'high' since this is choking Stem, and probably anything that'll read the CollecTor archives. I'll check with Karsten about how we want to handle the bad data on our end.
There's two bugs here: first that the Pleiades is publishing this and second that the DirAuths are allowing malformed data into the consensus.
Cheers! -DamianTor: unspecifiedhttps://gitlab.torproject.org/legacy/trac/-/issues/16858Non-ascii country code in extrainfo descriptor2020-06-13T15:30:35ZDamian JohnsonNon-ascii country code in extrainfo descriptorHi, starting recently (fifteen hours ago) torzurwelt started publishing extrainfo descriptors with a non-ascii country code in its dirreq-v3-reqs lines...

Not sure how these are slipping in but pretty sure the authorities should reject these as malformed.Tor: 0.3.1.x-final
