I worked with someone who observed that turning PDF back into structured text was about as likely as turning hamburger back into a cow.

In order to find word breaks, the program needs the width of every character in the current font. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog)
