Comment (by slabbe):
Great, thanks for the documentation link. I just read all of it. I now see
the difference between unicode and utf-8, which I was seeing vaguely as
synonyms.
Surprisingly, whereas Sage returns {{{False}}}, in Python 2.6 and 2.7,
{{{ss == s}}} returns {{{True}}}:
{{{
#!python
>>> s = unicode('an accent : é', encoding='utf-8')
>>> ss = u'an accent : é'
>>> s == ss
True
}}}
That means utf-8 is the default encoding in Python 2.7 for unicode
strings. In more details:
{{{
Python 2.7.2 (default, May 30 2012, 14:00:43)
[GCC 4.6.3] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 'é'
'\xc3\xa9'
>>> u'é'
u'\xe9'
>>> unicode('é', encoding='utf-8')
u'\xe9'
}}}
But, in sage-5.0, latin1 seems to be the default encoding for unicode
strings :
{{{
sage: 'é'
'\xc3\xa9'
sage: u'é'
u'\xc3\xa9'
sage: unicode('é', encoding='latin1')
u'\xc3\xa9'
sage: unicode('é', encoding='utf-8')
u'\xe9'
}}}
I did not look at the patch yet.
