At the moment, decision of what to do is left to the calling
application, pyexiv2 doesn't apply any processing to string containing
Null bytes. I'm open to re-considering this behaviour though, provided
we have clear use-cases which would benefit from it.

Do you have examples of images with Exif values containing null bytes,
and do you know the reason for such values?
