Windows: redirect standard I/O and convert text to UTF-16
Preprocessor magic is used to redirect putc/fputc/fputs/printf/fprintf
to custom implementations.
The custom implementations try to figure out if we are printing to the
console and, if so, convert the resulting strings to UTF-16 and print
them through ConsoleWriteW. If the output is redirected to a file or
a pipe, the original (presummed) UTF-8 is kept.
Simply setting the console output codepage to UTF-8 does not work,
because the standard I/O facilities of MSVCRT either does not support
unicode (in non-wchar mode), or has half-broken support through fputs,
which can still break up multi-byte sequences through its internal
buffering.
Likewise, changing the codepage and using ConsoleWriteA, or trying to
use fputws did not work in a test VM either.
This approach is the one that worked most consistently among the
ones tried, but also has problems. E.g. it breaks when setting the
codepage to UTF-8 manually (using `chcp 65001`).
