What about the entry point? Because one of the issues mentioned in the article is about mainCRTStartup calling an ANSI API. Most of the Rust programs are linked with the C runtime. Does Rust make sure that the C library initialization is also done in Unicode APIs?

No but it doesn't use C library values so it doesn't matter. E.g. getting the command line arguments is done via calling `GetCommandLineW` so it doesn't use argv or argc.

This is actually necessary because Rust cannot assume it owns the entry point. E.g. a Rust library could be called from a C++ application or in a DLL, etc. So when someone calls `std::env::args` it asks the OS directly for the arguments instead of getting them from C.
