C++11 added support for raw string literals, such as:
R"foo(A " weird \"
string)foo"
Does C have such a thing? If so, in what version of the standard? C11? If not, does anyone know if it is being planed and if any compilers support it?

A rawstring is a string literal (prefixed with an r) in which the normal escaping rules have been suspended so that everything is a literal.
A "string literal" is a sequence of characters from the source character set enclosed in double quotation marks (" "). String literals are used to represent a sequence of characters which, taken together, form a null-terminated string.
C Language Undefined behavior Modify string literalAttempting to modify the string literal has undefined behavior. However, modifying a mutable array of char directly, or through a pointer is naturally not undefined behavior, even if its initializer is a literal string.
In C the type of a string literal is a char[]. In C++, an ordinary string literal has type 'array of n const char'. For example, The type of the string literal "Hello" is "array of 6 const char".
Does C have such a thing? If so, in what version of the standard? C11?
C (C90, C99, C11) does not support this feature or any other similar feature.
If not, does anyone know if it is being planed
I have no idea, but usually there is a strong resistance of C committee to include new features in C.
and if any compilers support it?
I just tested it and it is apparently supported with recent gcc versions as a GNU extension (compile with -std=gnu99 or -std=gnu11).
For example:
printf(R"(hello\nworld\n)");
compiles and gives the expected behavior.
