Hi C++ Unicode folks, literally asking for a friend (Christopher, on the To: line so please Reply-All)…

His project team wants to use UTF-8 in their code base and they hoped to switch to u8string[_view] and char8_t throughout, but they encountered two sets of limitations:

• In the standard, those types don’t seem to work with std::format and streams.

• On Windows, platform APIs interpret narrow characters using the active code page (e.g., std::cout emits mojibake, filesystem::path{std::string} UTF-8 paths are mangled or throw).

What’s the current best guidance for adopting UTF-8 in C++ code?

Thank you,

Herb
