The draft alludes to an alternative:

Concretely, this would mean using Scheme literals for the scalar
values like so:

... are all syntaxes equivalent to #\A.

In strings, they would need to be delimited by something, say ";":

"\#e65;BC" => "ABC"

(Gambit currently has the char literals, but not the strings, I

This would have the advantage of being in line with the regular
numerical literals, thus avoiding redundancy in the lexical syntax.
It is, of course, completely different from what C and Java have.
