A small bug in Dia v0.81

[Antti Salonen]

I have created two classes in an UML diagram and an association between
them. The association is called "k�ytt��", Finnish for "uses". When I save
the diagram in a file and reload it, the name is truncated to "k�ytt�"
(the last '�' is missing). I don't have the time to do more extensive
testing right now, but the problem didn't seem to occur without umlauts.
