German "Umlaute" in drag and drop

[Jan <jan dwrox net>]

Hello,

while developing a application with GTK3 and the C api, I have an issue 
with files/folder names which are beeing dragged and dropped into the 
window.

In particular its about "äöü" charaters inside the filename, I assume it 
is the same with the pathes.

I have a file chooser dialog in my application, which does open/access 
the files perfectly, even with the "Umlauts" (äöü) and all function 
handling the work, work as expected.

Only when the same file becomes dragged and dropped, the special symbols 
are mixed up.

From drag and drop I receive:

file:///home/jan/Schreibtisch/S%C3%A4chsische%20Zeitung.pdf

Instead of:
file:///home/jan/Schreibtisch/Sächsische Zeitung.pdf

The information is stored and retrieved like this, from a 
"drag_data_received" event, context.

"""

GtkSelectionData *selData;
gchar **uriList = gtk_selection_data_get_uris(selData);

"""

And is then processed to remove the "%20" characters which works fine.

But I haven't found a way how to get the variant which displays the path 
like I desire with Umlauts.

Perhaps this is more of a C question, but perhaps someone has a insight 
in case the problem comes from GTK3 and not C itself.

I tried writing a variant which replaces the writing form with the 
correct Umlaut symbol, but it just shows me a messed up filename.


Maybe anyone has an answer to this?

Regards

Jan
