Text encoding broken when reading .osm files

[sommerluk]

Steps to reproduce:

1.) Open JOSM.

2.) Create a new layer.

2.) Create a node.

3.) Add a tag to this node: “name=𠀐𠀑”. (The value is “\U20010\U20011”.)

4.) Save the layer.

5.) Close the layer.

6.) Open again the file that you have saved.

Expected result: The “name” key still has the same value.

Actual result: The “name” key has the value “𠀐𠀐𠀑”.

Comment: Note the the file is created correctly. But JOSM does not open it correctly again. I had the same problem also when opening Overpass querries in JOSM. Only when downloading directly from the OSM API, there seems to be no problem.

Please report this separately (and with an example) if it occurs again.
