The use of parenthesis gives compilation errors in some situations

[Danixu]

Description

Hello,

Trying to create a json using raw data written directly into the program code, I have noticed that when you finish an string by a parenthesis ")", the program won't compiles.

This example won't compiles:
json test = R"({ "a": "b)"})"_json;

Just adding an space to the end of the string solves the problem:
json test = R"({ "a": "b) "})"_json;

Reproduction steps

just add the above code to any part of your program.

Expected vs. actual results

The string will be threated as string instead to threat the parenthesis as a end of the JSON raw data.

Minimal code example

`json test = R"({ "a": "b)"})"_json;`

Error messages

The errors are similar to when you forgot to close a string or simililar. All the code below the above example gives sintax error. Even the Visual Studio Code intellisense starts to work wrongly and the formatter breaks the format of the json.

Compiler and operating system

Microsoft (R) Build Engine versión 17.1.0+ae57d105c para .NET Framework on Windows 11

Library version

3.10.5

Validation

• The bug also occurs if the latest version from the develop branch is used.
• I can successfully compile and run the unit tests.

See https://en.cppreference.com/w/cpp/language/string_literal.

This works as expected. Use a delimiter sequence.

(Please open a discussion for support requests in the future.)
