Urhoplayer.exe crash when playlist path contains special characters like ÅÄÖ


#1

I need to render the movie. So I’m passing arguments for example (urhoplayer.exe “D:\Projects\övrigt\playlists\20181105–103658–b2995b35-5383-466e-bdec-58625370912f” -x 600 -y 800 -WindowPositionX 7 -WindowPositionY 29) to uhro player. but it crash the urhoplayer. This is due to special characters in my playlist path. Is there any solution available for this ?

FWIW, it looks like it is Windows-specific problem. I could not reproduce it locally on Linux host, at least on my Fedora system.

I’m running on this Windows 10.

Anything in the log? Users/__YourUserName__/AppData/Roaming/Urho3D/logs/__ProgramYouRan___.txt

No logs. I’m just passing command line arguments to urho player.

urhoplayer.exe “D:\Projects\övrigt\playlists\20181105–103658–b2995b35-5383-466e-bdec-58625370912f” -x 600 -y 800 -WindowPositionX 7 -WindowPositionY 29

I found why this is happen on windows.
https://github.com/urho3d/Urho3D/blob/master/Source/Urho3D/IO/FileSystem.cpp (bool FileSystem::FileExists(const String& fileName) const)
here we have this check statement

#ifdef WIN32
    DWORD attributes = GetFileAttributesW(WString(fixedName).CString());
    if (attributes == INVALID_FILE_ATTRIBUTES || !(attributes & FILE_ATTRIBUTE_DIRECTORY))
        return false;

and it returns null if path with contains letters like ÅÄÖ

What’s your system codepage?

Switching to using the correct OS functions (MultiByteToWideChar) in the WString consversion will most likely fix it. The current EncodeUTF16 functions are codepage ignorant.
