VC++ 2013 now supports raw string literals. Note that it does not support Unicode string literals. A raw string literal allows you to avoid having to escape special characters which can be handy with HTML, XML, and regular expressions. Here’s an example usage.
auto s1 = R"(This is a "raw" string)";
Now s1 is a const char* containing the value – This is a “raw” string. It’s similar to the @ string literal support in C# although even that does not support embedded double quotes. So, what if you want to embed R”(…) in a string literal. In that case, you can use the following syntax.
auto s2 = R"QQ(Example: R"(This is my raw string)")QQ";
Now s2 contains – Example: R”(This is my raw string)”.
In this example, I’ve used QQ as a delimiter. This delimiter can be any string up to 16 characters in length. Raw string literals can contain newlines too.
auto s3 = R"(<tr> <td>data</td> </tr>)";
Eventually, whenever they add support for Unicode string literals as well, you will be able to combine them and have raw Unicode string literals.
