I installed my own Python 2.4 in /opt/python/. I don't know if the right
code.py is loaded, but here is the output :
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
$ ./python2.4
Python 2.4.1 (#1, Sep 11 2005, 01:37:26)
[GCC 4.0.2 20050821 (prerelease) (Debian 4.0.1-6)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> u"é"
u'\xe9'
>>> import code
>>> code.interact()
Python 2.4.1 (#1, Sep 11 2005, 01:37:26)
[GCC 4.0.2 20050821 (prerelease) (Debian 4.0.1-6)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> u"é"
u'\xc3\xa9'

Well, that works better :-) For code.interact(), you can read my
attached patch. I don't know if it the best way to fix the but.
But, the following code still bug in Python 2.4 :
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
$ cat python_unicode_eval_bug.py
#*- coding: UTF-8 -*-
print "One Unicode character: %u" % len(u"é")
print "One Unicode character (using eval) : %u" % eval('len(u"é")')
$ python2.4 python_unicode_eval_bug.py
One Unicode character: 1
One Unicode character (using eval) : 2
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
RexFi explains me that Python can't guess eval('len(u"é")') charset.
Yep, that's difficult: locale? charset encoding? This test doesn't
matter.
