Are you sure the files aren't already broken in CVS? I haven't used
CVS, but I understand it's easy to corrupt binary files in CVS by
forgetting to tell CVS that they're binary.
Subversion treats all files as binary and won't muck with them unless
you tell it to. For example, if you tell it to do line-ending
conversion (svn:eol-style property) or keyword expansion
(svn:keywords property) it will do this, even on binary files; this
will probably destroy most kinds of binary files, so you should not
ask Subversion to do these kinds of operations on binary files.
There's also the matter of the MIME type (svn:mime-type property).
Have you set the MIME type of these files to a text/* MIME type or a
binary MIME type? A good MIME type for PDF files for example would be
application/pdf.

That seems also to point towards improper svn:eol-style or
svn:keywords properties being used. What do you see if you say "svn
proplist -v Iometer.pdf"?
