Broken UI and 404 to files and directories with non-ASCII names

Body

Hi community,

I'm trying to explore a repository¹, but it seems that I can't access the files or directories listed there. I am consistently getting 404s:

Looking around, I found that every repository with CJK (or non-ASCII perhaps?) characters in its filenames/paths seems clobbered and inaccessible, to name but a few ²³⁴⁵.

I remembered accessing ⁵ just a few days ago, and back then it worked without problem. If it is GitHub's problem, it's likely a recent regression.

Update 1: I filed a ticket for this, but have not heard back from GH yet.

Update 2: There is an automated incident thread at https://github.com/orgs/community/discussions/188156.

Update 3:

Update - We have mitigated the issue but are working on invalidating caches in order to fix the issue for all impacted repos.
