That matches my understanding.

I suppose a question I could add is whether anyone would like to see a
new character set introduced for diagnostics. My intuition is that it
would be a pretty heavy hammer to bring to bear and that the basic
source character set is probably Good Enough (tm).

Wouldn't these diagnostics be the place people are more likely to use non-basic source characters, though? When it comes to identifiers people will sometimes compromise and restrict themselves and e.g. avoid diacritics, but in error messages I feel like it makes a lot more sense to want to write with the full expression of their native script.
