I don't see a reason to restrict use of these characters in that
context; other symbols are permitted.
If the related wording is changed, please note that it appears twice in
the standard; in [lex.string]
<http://eel.is/c++draft/lex.string#nt:d-char> and in [gram.lex]
<http://eel.is/c++draft/gram.lex> (I hope/expect the latter is generated
from the former, but I don't know that for sure).
