+Yes, it's also somewhat strange to me that I ended up with two variations of this filename (by UTF-8 encoding) on disk.
+
+The filesystem is the default modern macOS one (APFS, case preserving but case insensitive).  From a quick experiement, it looks like the encoding of \"a with circle above\" is one of the \"case preserving but case insensitive\" things of the APFS file system.  Ie, I can create either variation, but which ever variation is created first is treated the same as the other variation when it comes to opening/updating the file.  Which I guess makes sense, as they're two different UTF-8 encodings of ultimately the same glyph.
+
+FWIW, I also noticed while investigating this, this morning, that the encoding on disk in my annex had switched back to consistently encoding in both my linked copy (2023-11-03) and the annex archive directory (2023-11-04).  So with the two versions known to the annex, it feels like I might be seeing a \"first to be created\" race in the UTF-8 encoding used when sync runs.
+
+Also FTR, in addition to the possibility that the podcast RSS changed encoding between the two runs, it's also possible that this got canonicalised by, eg, shell expansion, around 2023-11-03 / 2023-11-04; it definitely looks like I did a bunch of automated \"git mv ...\" to fix up filenames around that point.  (And then possibly the next git annex podcast fetch re-learnt the other name.)
+
+Since I seem to have stablised on one encoding no disk right now, I'm going to try to make git-annex forget about the other encoding of the name, to tidy up this particular confusion for now.
+
+But I agree it would be helpful to have a command variant that can accept the octal-encoded byte sequences (now) output by `git annex list`.  Both for cases like this, and in general for round tripping output back to input (something I do in some cases to handle scripted checks on annexed files against other things).
+
+Thanks for the reply,
