Generally postscript files may contain binary data.
Think of included images or font data.
So in postscript files there should normally be no utf-8
encoded text, but binary data are quite usual.
Think of postscript files as a sequence of ubytes.
As far as I know, images and font data have to be in clean7bit
too (they are not human readable though). But postscript files
can contain preview images, which can be binary. I know about
this. I just tried to keep my question simple -- and actually I'm
only testing part of the postscript file, where I know, that
binary data must not occur.
