In principle, that's correct.  However, the specific representation
that was picked for the string escape sequences is the way it is (if I
understand Matthew correctly) because of compatibility with C and/or
Java.  Going to a fixed number of digits would be an improvement,
IMHO, but it would break that compatibility.

If we're going to break compatibility, we might as well pick some
other representation, was my thinking, especially as I like Marc's
method of using the regular numeric literals.

I'd be having trouble remembering which of x, u, U is 2, 4, 6 digits
respectively.
