Hi fellows.

I can't search some partners from my android client.

On Server Log:

from my android client:
'execute' '('erp', 1, 'admin', 'res.partner', 'search', [('name', '=', '\x1a\x1a\x1a\x1a\x1a \x1a\x1a\x1a\x1a\x1a 1')])'

from OpenERP Client:
'execute' '('erp', 1, 'admin', u'res.partner', 'search', [('name', 'ilike', '\xd0\x9d\xd0\xb0\xd1\x80\xd0\xb0\xd0\xbd \xd0\xa2\xd1\x80\xd0\xb5\xd0\xb9\xd0\xb4 1')])'

Can anyone help me ?.
