Problems with non-ascii paths in FileDialog in SWT GTK [message #521584]

When I use org.eclipse.swt.widgets.FileDialog to choose a file in a path that contains non-ascii characters (like ä, ö, ü), the open() method just returns null instead of the path.

Stepping into the code, I found that the reason is in method computeResultChooserDialog(): the call to OS.g_filename_to_utf8 returns null (Line 152 in the FileDialog contained in org.eclipse.swt.gtk.linux.x86_64_3.5.2v3557f.jar).

My system is Debian Squeeze for x86_64 with Kernel 2.6.32 and GTK 2.18.6. Eclipse and SWT are of version 3.5.2. I am not sure, whether this is an SWT or a GTK problem. I checked, that the problem does not exist in Windows 32-bit.

Is this a known issue? I didn't find anything in newsgroups or bug reports. Am I missing something, an option I should set, for example?

Hi,

On non-Windows OSs g_filename_to_utf8() is dependent on the locale you're
running with. I would guess that your locale is not one that supports this
character (for instance a UTF-8 locale should be good, the C locale should
not). Does this seem to be the problem you're seeing?

Hi Grant

My locale is set to ISO-8859-1, which supports those characters. I also know that handling such path names worked in an earlier version of SWT and/or GTK.

Perhaps it used to work if you were using a gtk version < 2.4.10, because
the native file chooser that swt uses changes according to this. It's
probably a bug in swt, so I would suggest logging a report with swt at
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Platform &component=SWT ,
and specify the locale that you're using so that whoever investigates it
will not assume the same problem that I did.
