22031	Exception on Umlaute in file or folder name	Helferlein2	team	"==== What steps will reproduce the problem?
1. Run JOSM on Linux.
2. In the home directory (here on file system ext4),
- have a file or folder with a name containing an Umlaut (or more), e.g. ""Hörbücher""
- or create one, e.g. with ""$ touch AäOöUü.umlaute"".

3. In JOSM, select File > Open...

==== What is the expected result?
- The Open dialog with file names appears.

==== What happens instead?
- For every Umlaut in the name, the popup ""You have encountered a bug in JOSM"" appears.
- The Open dialog with empty file area is shown.
- InvalidPathException (see below)


==== Please provide any additional information below. Attach a screenshot if possible.

Notes:
- The Umlaute are correctly shown as such on the console, in KDE's Dolphin and DoubleCommander.
- The file name, put into a file with ""$ ll AäOöUü.umlaute > Umlaute.txt"" and looked at with a hex editor, appears as ""41 **C3 A4** 4F **C3 B6** 55 **C3 BC** 2E 75 6D 6C 61 75 74 65""
