Fixes crash when trying to print spanish accented letters like 'á'.

	Traceback (most recent call last):
	  File "./exitwp.py", line 353, in <module>
	    data = parse_wp_xml(wpe)
	  File "./exitwp.py", line 164, in parse_wp_xml
	    'items': parse_items(),
	  File "./exitwp.py", line 127, in parse_items
	    body = gi('content:encoded')
	  File "./exitwp.py", line 120, in gi
	    print result
	
	UnicodeEncodeError: 'ascii' codec can't encode character u'\xe1' in position 236: ordinal not in range(128)

Now is will display an encoding error on the writing of the files (not resulting on a crash anymore).

 Parse error on: Tutorial: Using luabind to integrate Lua with C/C++ (pt.2)

This fix could still be improved to fix the writing but don't really have the time right now.
