Add automatic utf-8 decoding for strings typed into the Python Console.

Other information:
When inputing some utf-8 encoded text, it's evaluated as a byte string instead, meaning it's not decoded as it should and as it effectively is in an external "python" or "ipython" ran into a gnome-terminal.

Here is some example to reproduce and understand the bug:

1/ in a gedit Python Console:

  >>> ch = u"Stéphanie"
  >>> ch
  u'St\xc3\xa9phanie'
  >>> print ch[2]
  Ã

2/ in a "python" command run in a terminal:

  >>> ch = u"Stéphanie"
  >>> ch
  u'St\xe9phanie'
  >>> print ch[2]
  é

We could explicitly ask for input decoding using """ch = 'Stéphanie'.decode('utf-8')""" and that works, of course, but I think it should be managed at the gedit plugin level instead, since the whole Gnome environment is using Unicode and the plugin should be aware of that.

Now, about some solution, here is what I did to correct this problem, but I'm not (yet ;-) ) a Python expert, so...

sudo sed -i -e '/get_text(inp, cur)$/s/$/.decode('utf-8')/' /usr/lib/gedit-2/plugins/pythonconsole/console.py
sudo python2.5 /usr/lib/python2.5/py_compile.py /usr/lib/gedit-2/plugins/pythonconsole/console.py

Explanation: add explicit 'utf-8' decoding anywhere the code get the text input from the Python Console interface.
