QGIS polygonize error 4 "file does not exist in the file system"?

Question

When I try to convert a raster DEM (in .asc or geotiff format) to polygons I get the error below:

ERROR 4: `Y:/GIS/oversvmmelser/tmp/out.tif' does not exist in the file system, and is not recognised as a supported dataset name.

Any idea what the problem is?

Typo in the path? oversvmmelser. Actually there is another path in the screen capture. It looks like QGIS eats the scandinavian characters. Use ASCII paths instead. — user30184, Commented Sep 3, 2014 at 9:59
Thanks @user30184. that solved it. Non ASCII characters, what a rookie mistake. — HC Haase, Commented Sep 3, 2014 at 10:33
One may also think that it is a bug in QGIS. Drop a mail to qgis-users mailing list. This is perhaps about the same: hub.qgis.org/issues/9080 — user30184, Commented Sep 3, 2014 at 10:40
well you are right. But in my experience this is a generic GIS bug. — HC Haase, Commented Sep 3, 2014 at 10:49

@user30184 came with the solution.

the (quite common GIS) problem was that non-ASCII characters (like æ ø å) in the path name gets deleted.

only use ASCII characters in file paths.
