           Summary: Hex and octal string values not completely specified
           Product: D
           Version: 2.023
          Platform: PC
               URL: http://www.digitalmars.com/d/2.0/lex.html
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2

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

Also, if you define arbitrary binary data that is not valid utf-8, should an
error reported when the 'd' suffix is processed by the compiler?

If the spec more clearly says that the stuff between quotes is treated as if a
UTF-8 string is created before suffixes are applied, then I think it formalizes
the intent.
