Umlauts and special chars get destroyed

Hey there,

I'm glad having found exif module, unfortunately I can't use it as it is at the moment.
Problem is that the Exif data of my images contain many german umlauts (ä, ö, ü, ß) - and those get destroyed when they're imported via exif module.
Here are 2 examples of what's happening:
"ä" -> "Š"
"ü" -> "Ÿ"

Umlauts and special chars are nowhere else a problem and I'm using them successfully everywhere.

I'd like to have a look at how the Exif data is represented in the database, but I didn't figure out, where it's store. Seems like it gets saved as binary data, could that be a cause of problem somehow?

Regards,
Daniel
