/*!
|
|
* \brief Returns \a path in the platform's native encoding.
|
|
* \remarks
|
|
* - On Windows we store paths internally as UTF-8 strings. So it is assumed that \a path is UTF-8 and a UTF-16
|
|
* std::wstring is returned.
|
|
* - On any other platforms we store paths internally using the native format (usually UTF-8). So it is assumed
|
|
* that \a path is already encoded as intended and passed as-is.
|
|
* - This function does basically the same as libstdc++'s `std::filesystem::u8path` implementation. However, the
|
|
* C++ standard actually imposes a conversion to UTF-8 when a non-UTF-8 narrow encoding is used. That's not
|
|
* wanted here. Besides, that function is deprecated in C++ 20.
