unicode error in SilverCity

[cboos]

I was looking for one of the SilverCity error that cmlenz told me about on IRC:

As we can see, the enscript renderer succeed on the same input.

I don't see any reference to SilverCity at all in that log message...

[cboos]

Right, I pasted the wrong stack trace (mixed up with #3065...)

I returned to the log, found some of the SilverCity related errors and adjusted the description accordingly.

(btw, jonas, guess where's the u'\xf6' coming from :) )

[jonas]

Yeah I've seen that error a million times :) It should be fixed in r3420 anyway.
