You are most probably aware of this utility:

The CSCD Conversion Utility (CSCDCONV) is designed to be used with the
Vipassana Research Institute's Chattha Sangayana CD-ROM. For information
on obtaining the CD, see:
http://www.tipitaka.org or http://www.vri.dhamma.org

For the latest version of this program, see:
http://www.fsnow.com/pali/

The output files produced by CSCDCONV are for personal use, and SHOULD NOT
BE DISTRIBUTED.

CSCDCONV may be distributed freely.

I have it, but don't use it. What might be useful is a utility that
converted the files to Unicode.
