I has tried to start odoo,  select my language (russian) in preferences and make wrong operation. Log:

 raise osv.except_osv(_('Invalid Action!'), _('In order to delete a confirmed sales order, you must cancel it before!'))
except_orm: (u'\u041d\u0435\u0432\u0435\u0440\u043d\u043e\u0435 \u0434\u0435\u0439\u0441\u0442\u0432\u0438\u0435!', u'\u0414\u043b\u044f \u0442\u043e\u0433\u043e

All ok, but i prefer to see understandable (Cyrillic) symbols instead \uXXX. One way for this i found is changing interface language (preferences -> english).

What i tried (without success):

LANG=C odoo ... 

I'm sure my console supports unicode symbols. 

Maybe i should add any options to /etc/odoo/openerp-server.conf for my purposes?

Thanks in advance.
