My locale's encoding is ISO8859-2.
I have a directory called (for example) "ßßß".
The file list pane shows the name correctly.
But when I cd into that directory, the location bar shows a round red alert
sign and three boxes with (if I see properly) FFFD.
If I rename (via F2) the directory from ßßß to ßßßß, then Thunar uses
UTF8-encoding - despite that the locale is NOT UTF8 in any way.
Now the directory name is showed ßßßß both in file list view and (when cd-ed
into) in the location bar. But, ls-ing in a terminal, the file name is showed
"Ă?Ă?Ă?Ă?". (So I have to rename it back in the terminal to a proper ISO8859-2
Thunar's version is 1.6.3, my Ubuntu is kept up-to-date.
