Thanks for the example Christian. I finally got it to work.
In an effort to emulate your example I ended up creating two new folders on my desktop “latin1” and “utf8”. I moved my files into the “latin1” folder and executed this modified version of your code in the terminal:
find /Users/galt/Desktop/latin1/ -type f -execdir sh -c 'iconv -f iso-8859-1 -t utf-8 "{}" > /Users/galt/Desktop/utf8/"{}"' ;
