Bug ID: 52223
           Summary: activeCodePage utf-8 in application manifest not
                    respected
           Product: Wine
           Version: 6.22
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: fusion
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Starting[1] with Windows 1903 (Windows 10 May 2019 update), Windows has allowed
applications to opt-in to supporting the UTF-8 code page by defining
"activeCodePage" in their application manifest. When in this mode, the "ANSI"
-A WinAPI functions operate in UTF-8 mode.

<activeCodePage
xmlns="http://schemas.microsoft.com/SMI/2019/WindowsSettings">UTF-8</activeCodePage>

WINE, even when winver is set to "win10", does not respect this application
manifest key, resulting in the application starting with a legacy code page.

This can cause issues if the user expects to work with files or strings not
supported in the active legacy code page. Often characters that cannot be
represented in the code page are replaced by question marks.

I am using the staging release of 6.22.

https://docs.microsoft.com/en-us/windows/apps/design/globalizing/use-utf8-co...

Expectation:

When an application with activeCodePage set to "UTF-8" in the application
manifest calls GetACP(), the number 65001 (CP_UTF8) is returned. Strings
returned by WinAPI functions (eg, file paths) are encoded in UTF-8. Strings
provided to WinAPI functions are UTF-8 and display appropriately in the UI.

Observed:

GetACP() returned a number representing a legacy code page (eg, 1252). Strings
returned by WinAPI functions are in that code page. Characters that cannot be
represented are replaced by question marks.

Confirming. Do you know of a specific application that depends on this?

There's a few applications I'm aware of that use this in their application
manifest. Rufus uses it when displaying filenames in the UI. Cataclysm-DDA and
Filmulator being cross-platform applications use it to display
internationalized strings.

The application I'm working on, Mixere[1], uses this functionality to support
UTF-8 to be able to open files with characters outside the legacy code page,
and display UTF-8 strings in the UI.

As this is also the listed alternative to Boost.Nowide[2], so I would not be
surprised to learn of more applications in the future.

activeCodePage is implemented now, marking fixed.

This will probably reveal bugs in other parts of Wine, please file new bugs for
any remaining codepage conversion issues.
