Special characters not handled

This:
```
OSSUnixSubprocess new
	command: '/bin/ls';
	arguments: #('-la' '/net/pirx/srv/nfs/music/Electro/Röyksopp');
	redirectStdout;
	runAndWaitOnExitDo: [ :process :outString  |
		outString inspect
	]
```
doesn't work. I guess it is because of the umlaut.
