Bug Summary and Steps to Reproduce
Bug Summary:
When writing std::string utf8_str = "\u{1F604}";
into a cpp file, the language server says incorrectly formed universal character name C/C++(965)
however compilation and execution works fine.
Steps to reproduce:
- Create a cpp file an copy/paste this code:
#include <iostream>
int main() {
std::string utf8_str = "\u{1F604}";
std::cout << "UTF-8 string: " << utf8_str << std::endl;
return 0;
}
- Compile it, I'm using g++ compiler
Expected behavior:
No error

Note \u{n...} (since C++23)
-> code point U+n... (arbitrary number of hexadecimal digits)
My compiler is using C++17 and works, also tried to change cppStandard
to gnu++23 but still persist the error
