I am sorry sotys..actually i am very much new to python..
import re
import os, sys

string = 'riché'
print string


def strip_accents(string):
  import unicodedata
  return unicodedata.normalize('NFKD',
unicode(string)).encode('ASCII', 'ignore')


msg=strip_accents(string)
print msg

Output :

sys:1: DeprecationWarning: Non-ASCII character '\xc3' in file regu.py
on line 4, but no encoding declared; see http://www.python.org/peps/pep-0263.html
for details
