The spec implies that a string literal containing hex and octal values is
assembled in UTF-8, but doesn't say so explicitly.  The text says that hex and
octal values can be used to build binary data.  If you have something like:

dstring ds = "\U00101234\x7f"d

what are the actual bytes in the string ds?  Without defining explicitly, it
allows for

00 10 12 34 7f 00 00 00 

on a big-endian machine as opposed to the probably intended

00 10 12 34 00 00 00 7f
