camiónCataluña.png - not reproduced on Windows 7, Inkscape 0.48.3.1.
- attached is a png file saved using Export Bitmap.
- just for clarification, is it only the file that has non-Ascii characters, or do the directories also have non-Ascii characters?
yes, I have the same problem with "save as" Cairo PNG.
other export formats, such as .emf and .svg appear to work correctly.
It might be a good idea to file this as a bug report at: https://bugs.launchpad.net/inkscape
