1422. Type of character literals containing universal-character-names

Section: 5.13.3  [lex.ccon]     Status: dup     Submitter: Dave Abrahams     Date: 2011-12-03

The treatment of character literals containing universal-character-names is not clear. It is reasonable to conclude from 5.13.5 [lex.string] paragraph 15 that if a character named by a UCN cannot be represented by a single character in the runtime character set, it becomes a multibyte character and thus such a character literal is a multicharacter literal, with type int and an implementation-defined value. It would be nice if 5.13.3 [lex.ccon] had the complete story by itself or at least a reference to 5.13.5 [lex.string] for the details.

Rationale (February, 2012):

This issue is a duplicate of issue 912.
