@guewen About the language of the qweb report, by default, if you don't have the block of XML code like https://github.com/odoo/odoo/blob/8.0/addons/account/views/report_invoice.xml#L149 then the report is generated in the language of the user, so if the user is not using English, then the report will be translated.
