How to install translated database strings?
I managed to install CiviCRM in Joomla with the database translated strings, but I had to replace the civicrm_data.mysql file with the content of the civicrm_data.fr_CA.mysql file.

Here is what I did, step by step, in case someone else is trying to accomplish the same thing:


Uncompressed both civicrm-4.7.2-joomla.zip and civicrm-4.7.2-l10n.tar.gz in /tmp
Unzipped /tmp/com_civicrm/admin/civicrm.zip and deleted the zip file.
Copied /tmp/civicrm/l10n/fr_CA/LC_MESSAGES/civicrm.mo into a newly created /tmp/com_civicrm/admin/civicrm/l10n/fr_CA/LC_MESSAGES/ directory.
Copied /tmp/civicrm/sql/civicrm_data.fr_CA.mysql as /tmp/com_civicrm/admin/civicrm/sql/civicrm_data.mysql (overwriting the original file)
Zipped directory /tmp/com_civicrm/admin/civicrm as /tmp/com_civicrm/admin/civicrm.zip and deleted the directory.
Pointed Joomla to install from the /tmp/com_civicrm directory.
Once installed, from Joomla's control panel, went to CiviCRM - Administer - Localization - Languages and changed the default language to français (Canada).


That's it!  CiviCRM en français !  I don't know if there is an easier way, but that's the only solution I found working.
