We are happy to announce that Arabic has been added to the list of translation projects for xTuple ERP, thanks to the recent contribution of a community member in Egypt. To download this translation or to join the project and help with the remaining work, please visit http://www.xtuple.org/translate.
One note for anyone who wants to use the Arabic .QM file at their site. To ensure that the translation reads properly in xTuple ERP (that is, from right-to-left), you will need to launch the xTuple application from the command line with the following parameter: -reverse. If you do not add this option when launching xTuple ERP, the translated text will not display in the proper direction.
This is a known issue, as reported here: http://www.xtuple.org/issuetracker/view.php?id=9023. Our developers will be working to include bi-directional lanugage support into the application so that in the future you will not need to use a command line parameter when starting the application.
