I don't agree with you on this point, but maybe I'm wrong. Take a look at this. Following what I understood from your email, if I set the encoding inside the Python script I won't have this problem, right? [humitos@michifus ~]$ cat test.py #!/usr/bin/python # -*- coding: utf-8 -*- s = 'camión' print 'UTF-8, set by the first line in the script' print 'len:', len(s) print 'last but one letter:', s[-2] print 'second to last:', s[-3] print s = u'camión' print 'Unicode' print 'len:', len(s) print 'last but one letter:', s[-2] print 'second to last:', s[-3] [humitos@michifus ~]$ python test.py UTF-8, set by the first line in the script len: 7 last but one letter: � second to last: Unicode len: 6 last but one letter: ó second to last: i [humitos@michifus ~]$ Changing the default encoding, as you said, is dangerous because we will be hiding the problem instead of resolving it. gtk people say this on the comments in the ticket that manuq reported. So, the right way to handle and manipulate strings is using Unicode, with the "u" at the beginning of each string. That is the recommended way to do it. This is not me, I mean, it is not a whim. There are many reasons to use Unicode.
