   I did a little developement on PDF-s.  For debugging is is convenient   
   to have 100% printable form, such PDF-s are perfectly valid.  Adobe   
   encourages putting in a bunch of nonprintable characters to   
   discourage silly tools from "converting text encoding", which   
   would mangle PDF-s.
