Bug ID: 56597
           Summary: Wine does not recognize ANSI escape codes
           Product: Wine
           Version: 9.7
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ucrtbase
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Created attachment 76355
  --> https://bugs.winehq.org/attachment.cgi?id=76355
binary file to reproduce

According to
[Wikipedia](https://en.wikipedia.org/wiki/ANSI_escape_code#DOS_and_Windows) and
[Windows API
docs](https://learn.microsoft.com/en-us/windows/console/console-virtual-terminal-s...),
Windows has supported ANSI escape code since Windows 10 version 1511.

```c
#include <locale.h>
#include <stdio.h>

int main () {
    setlocale (LC_ALL, "");
    fprintf (stdout, "\x1b[32m" "\x1b[1m" "STDOUT" "\x1b[0m" "\n");
    fprintf (stderr, "\x1b[31m" "\x1b[1m" "STDERR" "\x1b[0m" "\n");
}
```

For this example (compiled with clang 18 in msys2, linked to `ucrtbase.dll`),
the characters can be escaped with color and bold and output as we expected
under Windows. However, run these program in wine will directly print out the
escape code without escaping:

```
[32m[1mSTDOUT[0m
[31m[1mSTDERR[0m
```

It seems that this bug report includes more information than bug 52850, would
it be better to move to here?

It's not an issue of wine console, I tried to run the attached example in KDE's
konsole and it doesn't work. I think it's a bug of `ucrtbase.dll` that wine
have not followed the changes of Windows in Windows 10 1511.

doesn't matter much... the issue is well known

I tested your recompiled C sample, with ucrtbase, on xfce console & xterm and
it works as expected.
what makes you think that ucrtbase is to blame?

Did you compile it with winegcc or mingw-w64?

????????????Maybe it's wrong.

I just infferred from the if you need to use ANSI escape code in old windows
versions, you need to additionally call the Windows API, but after the Windows
10 1511 update, you no longer need to.

Now it looks like more verification is needed to figure it out.????
