[Voted into WP at March, 2010 meeting.]
Proposed resolution (October, 2009):
Change 5.3 [lex.charset] paragraph 2 as follows:
Additionally, if the hexadecimal value for a universal-character-name outside a character or string literal corresponds to a control character (in either of the ranges 0x00-0x1F or 0x7F-0x9F, both inclusive) or to a character in the basic source character set, the program is ill-formed.
Notes from the July, 2009 meeting:
The CWG supported a resolution in which the d-char-sequence of a raw string literal is considered to be outside the literal and thus, by 5.3 [lex.charset] paragraph 2, could not contain a UCN designating a member of the basic source character set.
Since members of the basic source character set can be written inside a string using a universal character name, it is not clear whether a UCN that represents ']' or one of the characters in the terminating d-char-sequence should be interpreted as that character or as an attempt to “escape” that character and prevent its interpretation as part of the terminating sequence of a raw character string.
