------- Comment #3 from eric dot niebler at gmail dot com 2008-12-07 00:46 ------- If you are referring to 2.1/1 ...
"Physical source file characters are mapped, in an implementation-defined manner, to the basic source character set (introducing new-line characters for end-of-line indicators) if necessary. Trigraph sequences (2.3) are replaced by corresponding single-character internal representations. Any source file character not in the basic source character set (2.2) is replaced by the universal-character-name that designates that character. (An implementation may use any internal encoding, so long as an actual extended character encountered in the source file, and the same extended character expressed in the source file as a universal-character-name (i.e. using the \uXXXX notation), are handled equivalently.)" I read this as permitting a mapping of characters, but not a deletion of characters, which is what gcc is doing. The only deletion of characters I see permitted is the deletion of a newline and an IMMEDIATELY preceding backslash. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38433
