digitalmars.D.learn - How to correctly display accented characters at the Windows prompt?

reply Cleverson Casarin Uliana via Digitalmars-d-learn writes:
Hello, when I run a compiled Windows executable at the console,
letters outside the ascii range such as ç and ã do not display
propperly. Is there any d function to change the console code page on
the fly? My Windows console code page, which is for Brazilian
Portuguese, is at 850. Perhaps an alternative would be to convert d
strings from Unicode to the 850 code page on the fly.

Thanks,
Cleverson

Call SetConsoleOutputCP(CP_UTF8).

Hello John and all, how do you search for a given function to see
where it is defined/declared? I tried to find SetConsoleOutputCP by
myself, but the search embeded in the documentation cannot find
anything in the phobos library refference, and searching the entire
site returns forum posts only.

Thanks,

It looks like it's in

    core.sys.windows.wincon;

No, this may appear to to work, but in reality, it's broken. The 
only reliable way is to convert to the native windows codepage.

Hi Martin, indeed, here in my workplace Windows machine there is no
"CP_UTF_8" codepage, nor there is 65001. I was waiting to try it later
on my home machine, but since you say it's broken, then I'll need to
look for a way to convert the actual string to the 850 codepage...

Just for info, this is probably a d related bug, because the Racket
language for example has a (reencode-output-port) function, and it
Works.

codepage 65001 (UTF8) should be available on all modern Windows. 
You can try command cp 65001 in the console window (and change 
your font accordingly).

I don't know know about Racket, but D's problems are related to 
the C runtime library. Here is what I found out:

-m32 (uses DM C library): output to stdout works, but stderr is 
broken (corrupt accented characters, or total output freeze).
https://issues.dlang.org/show_bug.cgi?id=1448

-m32mscoff and -m64 (Microsoft C runtime): broken characters and 
some mysterious failures.
https://issues.dlang.org/show_bug.cgi?id=15761

So this leaves transcoding as the only viable solution. Luckily, 
there is std.windows.charset.toMBSz function you can use.
