The C++20’s u8/char8_t Backward-Compatibility Fiasco
Summary
The article argues that C++20's u8 and char8_t break backward compatibility, presenting a real-world example where code compiling under C++17 fails in C++20 due to the u8 string literal changing to a char8_t array. It discusses migration challenges for large codebases and suggests avoiding the u8 prefix when possible, referencing Google's C++ Style Guide.
