Perhaps it is time to re-title this paper to "Rewrite [lex.ccon] and [lex.string]" :)
An update of D2029R3 is available at https://rawgit.com/sg16-unicode/sg16/master/papers/d2029r3.html. This addresses the feedback provided at the July 20th, 2020, core issues processing telecon. The relevant changes include:
- Changed the introductory and proposed resolution overview to remove incorrect uses of "narrowing integer conversion" in prose intended to describe something more like an "integral conversion".
- [lex.ccon]pY: Added footnotes explaining that, for nonencodable character literals and multicharacter literals, the associated character encoding may be used solely to determine encodability and not to actually encode values.
- [lex.ccon]pZ: Merged Z.1 into the introductory text to make the short circuiting behavior clear and renumbered the remaining subparagraphs.
- [lex.ccon]pZ: Specified that the determination of a character literal value during translation phase 4 uses the range of representable values of the character literal's type in translation phase 7.
- [lex.string]pX: Added normative wording stating that the n that appears in the string literal array type corresponds to the number of encoded code units.
- [lex.string]pZ: Elevated notes related to stateful character encodings to normative encouragement.
I believe this is ready for CWG review again. Jens, Richard, and Hubert, if you can provide any additional change requests before the next core issues processing telecon, I would appreciate it. I'm hoping that the next CWG review will be the last one!
