Bug ID: 51306 Summary: Wine-Mono doesn't show Japanese text (DllImport issue?). Product: Wine Version: 6.11 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: mscoree Assignee: wine-bugs@winehq.org Reporter: sagawa.aki+winebugs@gmail.com Distribution: ---

Created attachment 70171 --> https://bugs.winehq.org/attachment.cgi?id=70171 source and executable.

I wrote and ran a short program attached with Wine 6.11 and Wine Mono 6.20. But, it didn't work as expected. The code calls kernel32's GetDateFormatA by DllImport feature. I guess Wine-Mono's DllImport doesn't handle Japanese ANSI code page well.

Steps to reproduce: 1. If your 'locale -a' doesn't show ja_JP.utf8, add Japanese locale support to your environment. 2. Run today.exe on Japanese locale with wine, i.e. LANG=ja_JP.UTF-8 wine today.exe

Expected result: Message window shows today's date text in Japanese, e.g. 2021年6月21日.

Actual result: Message window appears, but shows no message text.

Remarks: If we use CharSet.Unicode instead, it works properly.

--- Comment #1 from Esme Povirk madewokherd@gmail.com --- It probably expects utf8 instead of the ANSI code page.

--- Comment #2 from Esme Povirk madewokherd@gmail.com --- Relevant code:

https://github.com/mono/mono/blob/284cb67f65098660f5764c8044f42c098cbe8934/m...

It seems ANSI marshaling was never really implemented, and they use UTF8.

--- Comment #3 from Esme Povirk madewokherd@gmail.com --- I wrote a fix: https://github.com/madewokherd/wine-mono/pull/107

Not yet committed because LPStr is used a lot, and changing it might break things.

--- Comment #5 from Esme Povirk madewokherd@gmail.com --- It passed the existing tests, but the new test failed on Windows due to heap corruption.

--- Comment #6 from Esme Povirk madewokherd@gmail.com --- I fixed the test case and pushed this to the develop branch. There's a risk that introducing a mismatch in string conversion via different methods will cause some problems, but I think we'll just have to deal with them as they come up.
