[OS X TeX] converting ligatures into text

  I have to extract text from a large number of PDF documents produced 
using TeX. Because (I presume) of TeX's non-standard font encodings, 
cut and paste often goes wrong. In particular, ligatures get garbled: I 
get di±cult instead of difficult.

Does anybody know of a program (or of a definitive set of replacements 
that could be given to Perl) for cleaning up such text?
