The char data won't be interpreted correctly when read as char16_t data. On Windows, wchar_t is also 2 bytes in size.

It's built into the language, so you don't need any headers. If it doesn't work, either your compiler doesn't support it, or you forgot to enable C++20 support (e.g. -std=c++20 in GCC). The problem here is possibly the compiler is not able to identify that this is a C++20 feature. irish road bowling syracuseWebApr 4, 2024 · I'm the author of the P0482 and P1423 char8_t proposals..
