You are right. Maybe I am overthinking about effects on VC++ not supporting UTF-8 and broken Win32 Console NLS. The former problem might not be M$'s fault, but the English-only library's author's. Also, not so many libraries have been ported to Windows correctly, in fact, if had been, M$ would not have made the LXSS. So it does not really matter. The latter one is M$'s, but some other UIs (eg. TextBox in WinForms) or IPCs (eg. files, pipes, sockets) can replace it. As a conclusion, avoid using fxxking VC++, English-only libraries and Win32 Console ourselves, and program happier.
