Yeah, if the original was bad and cannot be sanely expressed in
UTF-8, you have two options.  You can show the contents as raw bytes
recorded in the object with a warning so that the user can use it as
such (e.g. perhaps the original was indeed an iso8859-2 but was
incorrectly marked as UTF-8, or something like that, and a human
that is more intelligent than a tool _could_ guess and attempt to
recover).  Or you can error out and refuse to produce output.

We deliberately made a design choice to take the former option.
