(I've moved this to a new thread as it doesn't really have anything to do with the decade old one it was added to, other than involving similar Unicode characters.)
Can you provide some example filenames for us to try with? Maybe via a zip file or similar, assuming it preserves the unusual characters.
Without that, it's difficult to test things, since they don't occur in any normal situation.
Where are they coming from, anyway? It seems like something that should be fixed at the source. But it should also be possible to fix things via the Opus rename tool, if needed.
In fact, I would expect the "Make Safe Name" regex in Various simple rename presets to remove the unwanted characters already, without requiring scripting.
