Dude, I made a small change to your code (from_iso88591_to_utf8.sh) to expand more files:

#!/bin/bash

for file in `find . -regextype posix-egrep -regex ".*\.(html|jsp|jspx|java|properties|xml|sql|pck|fnc|trg)"`; do
  iconv -f ISO-8859-1 -t UTF-8 $file > $file.utf-8;
  mv $file.utf-8 $file;
done

Code in My Gists.
