Printing fails with accented characters (trunk)

[Dukai Gábor]

Hi!
Trunk version.
1.) Try to create a partner name with accented characters like 'ó' and use the print screen report on it. The result:
 Traceback (most recent call last):
   File "path/bin/service/web_services.py", line 465, in go
    (result, format) = obj.create(cr, uid, ids, datas, context)
   File "path/bin/report/printscreen/ps_list.py", line 76, in create
     res = self._create_table(uid, datas['ids'], result['fields'], fields_order, rows, context, model_desc)
   File "path/bin/report/printscreen/ps_list.py", line 169, in _create_table
    txt = new_doc.createTextNode(str(line[f] or ''))
 UnicodeEncodeError: 'ascii' codec can't encode character u'\xf3' in position 2: ordinal not in range(128)

2.)Trying to print a General Ledger where account names have 'č' in them:
