Answer 1

The solution is to add -municode to the compilation parameters, as mentioned by @ssbssa in a comment.

Example:

g++ helloworld3.cpp -o helloworld3 -Wl,-subsystem,windows -municode

See https://sourceforge.net/p/mingw-w64/wiki2/Unicode%20apps/

While it is not necessary to define _UNICODE or UNICODE to compile the above code, -municode is needed for linking because it uses wmain() instead of the traditional main().
