The standard doesn't specify what the new-line character is.
According to Unicode, the following codepoint sequences should be considered lines terminators
LF: Line Feed, U+000A
VT: Vertical Tab, U+000B
FF: Form Feed, U+000C
CR: Carriage Return, U+000D
CR+LF: CR (U+000D) followed by LF (U+000A)
NEL: Next Line, U+0085
LS: Line Separator, U+2028
PS: Paragraph Separator, U+2029
What I would like to do:
* Define new-line and white-spaces as grammar term, with an explicit list of codepoint sequences.
* In phase 2, replace all characters which represent a line termination with Line Feed (which is reverted later for raw string literals). this would notably fix https://wg21.link/cwg1655
* It would also help to mandate that trailing whitespaces are removed in phase 2
Does that make sense to anyone ?
