How this code fragment in print.cpp ever works?

The current file location:

STL/stl/src/print.cpp

Line 43 in 48db51b

const bool _Is_unicode_console = GetConsoleMode(_Console_handle, &_Console_mode) != 0;

- claims that return value of GetConsoleMode() says that console is Unicode. But that's not true, or I didn't understand something? Sorry for (possibly) stupid question

You can check the comment above this call, it says:

// We can check if _Console_handle actually refers to a console or not by checking the
// return value of GetConsoleMode().

If GetConsoleMode succeeds (returns non-zero), it means that the _Console_handle is a true console handle.
Maybe the name _Is_unicode_console is just a bit misleading.
