w32: Always use Unicode for console input and output.
* common/init.c (_init_common_subsystems) [W32]: Set the codepage to UTF-8 for input and putput. Switch gettext to UTF-8. * tools/gpgconf.c (main): Display the input and output codepage if they differ. * g10/gpg.c (utf8_strings) [W32]: Make sure this is always set.
With this patch the former patch to use ReadConsoleW and WriteConsoleW
in ttyio.c are kind of superfluous because the ANSI version of these
functions are also able to read/write UTF-8 directly given the console
code page has been set correctly. However, this seems to work only
with recent versions of Windows-10.
