postprocessing filter for archive files

[Oskar Bartenstein]

Is there simple way to run a filter on all newly generated
output files? Happy about any hint.

(Sorry if this is a trivial question. I am not familiar with Perl.
If I can run output files through a filter then it becomes
easy to produce archives _with_ Japanese characters and _without_
browser side guesswork.)
