The fonts in question are actually called "TEMPEST fonts" in the PGP documentation (or at least they were last time I looked - I haven't seen the docs for the Symantec PGP).   The bug here would seem to be the word "resistant".  TEMPEST should be capitalized, too.

Does anyone happen to have Symantec PGP and know if they even still do this?
