Embedding a literal "\u" in a unicode raw string.

Right. IMO, this is just a plain design mistake in the Python Unicode
handling. Unfortunately, there was discussion about this specific issue
in the past, and the proponent of the status quo always defended it,
with the rationale (IIUC) that a) without that, you can't put arbitrary
Unicode characters into a string, and b) the semantics of \u in Java and
C is so that \u gets processed even before tokenization even starts, and
it should be the same in Python.
