Rename non-ASCII filenames to readable ASCII, i.e. replace accented characters, etc (Python recipe) by ccpizza
ActiveState Code (http://code.activestate.com/recipes/577226/)

The script converts any accented characters in filenames to their ASCII equivalents. e.g.:

Example:

â > a
ä > a
à > a
á > a
é > e
í > i
ó > o
ú > u
ñ > n
ü > u
...

Before-and-after example:

01_Antonín_Dvořák_Allegro.mp3   >>>  01_Antonin_Dvorak_Allegro.mp3

Usage:

Running the script without arguments will rename all files in the current folder.
