Opening a Blu-ray ISO file containing accented characters (e.g. ç, č, é, etc.) in its file name fails

OS: Windows 10 Pro, Version 1709, OS build 16299.248 The behaviour might be similar on other platforms, but I did not try.

VLC versions tried:

• 3.0.1 (release build)
• 4.0.0-20180304-0508 (nightly build)

To reproduce:

• Open an ISO file containing Blu-ray content that contains special accented characters in its file name (e.g. 'François Truffaut.iso'), either through the 'Open File...' dialog or through the Windows Explorer 'Open with' context menu action.

Expected behaviour:

• The Blu-ray opens correctly, e.g. with a clearly visible menu.

Observed behaviour:

• The Blu-ray does not open and/or display properly.
• Behaviour varies with ISO file; the user might see just a black seen, or alternatively other unexpected content (e.g. https://imgur.com/a/3x1J0).
• Consistently reproducible, with various ISO files and file names.

Possible workaround:

• Removing special accented characters from the ISO file name (e.g. 'François Truffaut.iso' -> 'Francois Truffaut.iso') will restore expected behaviour.

Hello,

That is not surprising, since we had the same issue, in the past, with DVDs.

Can you share your complete logs, please?

Log demonstrating success. Blu-ray ISO with filename 'Francois Truffaut.iso' (no special character).

Log demonstrating failure. SAME blu-ray ISO with filename 'François Truffaut.iso' (simply renamed, with special character).

Hi Jean-Baptiste,

Sure! I have attached two logs trying to open the exact same Blu-ray ISO file. In one case, I have called it 'Francois Truffaut.iso', and in the other I just renamed it to 'François Truffaut.iso'. The accented character is the only difference. The former opens successfully, while the latter fails. Hope the logs will be useful in finding the root cause. Let me know if there's any other info that you might need.

Thanks.

I can't reproduce on linux.

libbluray & windows FS ?

added Component::Build system: Contribs label and removed Component::Input: optical media label

I met the same issue on WIN10. Can not open a BD file which name containing Chinese or Japanese character.

Probably Windows only, yes.

added Platform::Windows desktop label

I don't know about the behavior on non-Windows systems, but I can confirm that this issue still exists, as described above.

libudfread issue? It uses normal open(), maybe it should use _wopen().

Yes, it would seem to be the issue here. -> MultiByteToWideChar to get a WCHAR, and then _wopen()

See libudfread@0147883d and libbluray@f1939293

So, it should be fixed upstream, we'll wait for a release :)

And there is a tag for 1.3.0 on libbluray: https://code.videolan.org/videolan/libbluray/-/tags/1.3.0

changed milestone to %3.0.13
