I actually disagree with that. It is fairly easy to include non-ASCII characters in a raw Unicode string - just type them in.

That violates the convention used in many places that source code should only contain printable ASCII, and all non-ASCII or unprintable characters should be written using \x or \u escapes.

Or, if that fails, use string concatenation with a non-raw string:

r"foo\uhallo" "\u20ac" r"welt"

That makes for pretty unreadable source code though.

Looking for a third opinion,
