I think this is highly dependent on your OS environment. For example:
Python 2.4.3 (#1, Oct 23 2006, 14:19:47)
[GCC 4.1.1 20060525 (Red Hat 4.1.1-1)] o
Type "help", "copyright", "credits" or "
>>> import sys
>>> sys.getdefaultencoding()
'ascii'
>>> print unichr(163)
£
[p...@wildfire ~]$ echo $LANG
en_GB.UTF-8
...but:
LANG=C python
Python 2.4.3 (#1, Oct 23 2006, 14:19:47)
[GCC 4.1.1 20060525 (Red Hat 4.1.1-1)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> print unichr(163)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa3' in
position 0: ordinal not in range(128)
...i.e. here I can just print unicode characters, with nothing
particularly special, provided my environment variables are set right.
