Simple python script that converts all files in the given path from iso-8859-1 or ascii to UTF-8
just run:
./go2utf8.py path_to_some_dir
this will create a directory called converted that will have all the files from path_to_some_dir inside and converted.
This script was basically based on Sébastien RoccaSerra answer on StackOverflow: http://stackoverflow.com/a/192086/680611
