If your implementation can read:

	"\U+30AB.\U+309A."

doesn't that mean it should also read:

        (list #\U+30AB #\U+309A)

I'm not sure how to reconcile those.

I specifically mean the R6RS recommendations to _not_ preclude that
interpretation.  Yes, you should be able to read that string constant
from some Unicode stream and wind up with a one character string
constant.

If someone writes a non-portable program that says "This program
assumes that all string constants are Unicode [and, in such and such a
canonicalization form, etc.]" then that program wouldn't necessarily
run correctly on your implementation.
