Re: Use SetConsoleOutputCP on windows

[Marcus Mason <m4gicks@...>]

Perhaps I should clarify my intent here. I want lua to print correctly on windows, like all the other programming language binaries I use on my computer. Chez scheme, various _javascript_ envrionments, clojure, etc have no issues printing for me. Why is lua.exe not able to do it?

Setting the codepage to 65001 works most of the time, but this is not
a general solution, as output buffering can interfere.

You can try

    fputs( "\xc3\xbc", stdout );

vs.

    putc('\xc3'); putc('\xbc');

See https://stackoverflow.com/questions/45575863/how-to-print-utf-8-strings-to-stdcout-on-windows
or https://stackoverflow.com/questions/1660492/utf-8-output-on-windows-console
for further discussion (ignoring the C++ parts).

In summary: No, UTF-8 is not supported by the windows console.
