dotty is a very old program, and wasn't ever updated to use non-ASCII character sets.
So it won't work with your file. It probably won't ever be updated (though anyone is
welcome to try). We should probably remove it from the package. There are
probably we should remove it from the graphviz disrtibution. You might do better
with a more modern front end -- the choice depends on your operating system.

Some recommendations are Pixelglow UI for the Mac, Canviz, ZGRViewer.
