That’s a tough error. Rewriting the code to use vectors instead of strings would be a work-around but that’s tedious work.

According to https://en.cppreference.com/w/cpp/string/char_traits and https://en.cppreference.com/w/c/string/multibyte/char8_t I expect that changing set(CMAKE_CXX_STANDARD 20) to set(CMAKE_CXX_STANDARD 23) in CMakeLists.txt would eventually work. Could you try that?
