Unicode is confusing me

[Dick Moores]

As per p. 188 of Python for Dummies, I've created a sitecustomize.py
in my site-packages directory:

============================
# sitecustomize.py (see p.188 of Python for Dummies)
import sys
sys.setdefaultencoding('utf-8')
===============================

With that in place, at the interactive prompt this goes well:
===============================

import sys
sys.getdefaultencoding() 'utf-8'
a = [u'\u91cd', u'\u8981', u'\u6027']
for x in range(3):

.. . . print a[x],
.. . .
$B=E(B $BMW(B $B@-(B===============================
The 3 CJK characters are printed very nicely.

However, when I put the last 3 lines of that code in a script,

============================
a = [u'\u91cd', u'\u8981', u'\u6027']
for x in range(3):
print a[x]
===========================

and redirect the output to a text file, I get
"Traceback (most recent call last):
File "E:\Python25\dev\Untitled1.py", line 3, in ?
print a[x]
UnicodeEncodeError: 'ascii' codec can't encode character u'\u91cd' in
position 0: ordinal not in range(128)"

I thought maybe it would help if I made the first line,
# -*- coding: utf-8 -*-

but that made no difference. Got the same error.

Can someone help me understand what's going on?

Thanks,

Dick Moores
