            Bug ID: 60139
           Summary: cmd's type cannot handle UTF-8/16 correctly
           Product: Wine
           Version: 11.14
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Keywords: download, localization, source
          Severity: trivial
          Priority: P2
         Component: cmd
          Assignee: [e-mail]

Simple file

Wine's cmd's "type" built-in produces strings of nonsense when reading files
encoded as UTF-8 or UTF-16, presumably anything non-ASCII.

Attached is a simple file encoded as UTF-8.
Another example is using regedit /e to export keys from the registry, which are
encoded as UTF-16LE.

$ wine cmd
> type file
> A very simple file ^┬┤├ƒ┼é─æ\}╦Ç─æÔåÆ├ª├ƒ─º─æ[Ôåô├ª┬¿

The same file (or registry export) on Windows 10/11 look fine.

Adding a BOM doesn't seem to help (Bug 56160), and the BOM itself simply prints
as more garbage:
´╗┐A very simple file ^┬┤├ƒ┼é─æ\}╦Ç─æÔåÆ├ª├ƒ─º─æ[Ôåô├ª┬¿

$ wine cmd start /c type file
is a bit quicker.

Ah, Wine's cmd matches the behaviour in Windows 95 and NT 4.

is_ascii_out = GetConsoleMode(hOut, &console_mode);

Do I need to pass a switch to cmd?

type with UTF-8

With initial testing, the active code page(mapping from byte to character
values) is set to 437(Old DOS encoding). This can be obtained via the chcp
command without any arguments.

Changing to the code page 65001 by using `chcp 65001` and then executing type
on the UTF-8 encoded attachment works as expected. This behaviour is the same
as shown in Windows 10.

From wine's cmd:
Microsoft Windows 10.0.19043

Z:\var\home\rkbarath\wine-devel>chcp
Active code page: 437

Z:\var\home\rkbarath\wine-devel>type test_type\this
A very simple file ^´ßłđ\}ˀđ→æßħđ[↓æ¨
Z:\var\home\rkbarath\wine-devel>chcp 65001
Active code page: 65001

Z:\var\home\rkbarath\wine-devel>type test_type\this
A very simple file ^´ßłđ\}ˀđ→æßħđ[↓æ¨
Z:\var\home\rkbarath\wine-devel>

Indeed, chcp is the magic key.

I guess cmd should take the selected Windows version into account when choosing
which code page to default to.
