Python unicode: how to replace character that cannot be decoded using utf8 with whitespace?

How to replace characters that cannot be decoded using utf8 with whitespace?

# -*- coding: utf-8 -*-
print unicode('\x97', errors='ignore') # print out nothing
print unicode('ABC\x97abc', errors='ignore') # print out ABCabc

How can I print out ABC abc instead of ABCabc? Note, \x97 is just an example character. The characters that cannot be decoded are unknown inputs.

Take a look at codecs.register_error. You can use it to register custom error handlers

https://docs.python.org/2/library/codecs.html#codecs.register_error

import codecs
codecs.register_error('replace_with_space', lambda e: (u' ',e.start + 1))
print unicode('ABC\x97abc', encoding='utf-8', errors='replace_with_space')

You can use a try-except statement to handle the UnicodeDecodeError :

def my_encoder(my_string):
   for i in my_string:
      try :
         yield unicode(i)
      except UnicodeDecodeError:
         yield '\t' #or another whietespaces

And then use str.join method to join your string :

print ''.join(my_encoder(my_string))

Demo :

>>> print ''.join(my_encoder('this is a\x97n exam\x97ple'))
this is a   n exam  ple
