I upgraded Ubuntu 12.04 to 14.04 LTS and after having some problems not being able te print, which were solved with help from this community. I now have the problem I cannot print sales orders which have been created before the upgrade (also upgraded OpenERP).

But the new ones are printable. Error msg is :

ascii
4,00 Stuk(s
4
5
ordinal not in range(128)

(<type 'exceptions.UnicodeEncodeError'>, UnicodeEncodeError('ascii', u'4,00\xa0Stuk(s', 4, 5, 'ordinal not in range(128)'), <traceback object at 0x7fbea533a7a0>)

Log file says :

Hope this rings a bell for someone. Looking at this I would says it is complaining about the number of items and the uom used for that.
