* The Windows CRT and console are something else. In order for the

* console to get UTF-8 written to it correctly we have to bypass stdio
|
|
* completely. No amount of fflush()ing helps. If the first byte of a
|
|
* buffer being written with fwrite() is non-ASCII UTF-8 then the
|
|
* console misinterprets the byte sequence. But one must not
|
|
* WriteFile() if stdout is a file!1!!
|
|
*
|
|
* We carry knowledge of whether the FILE * is a tty everywhere we
|
|
* output to it just so we can write with WriteFile() if stdout is a
|
|
* console on WIN32.
