In addition to @[deleted] comment, let me mention that the templates are translated as well, but not every language is fully translated yet. The German language is at 100% (which I know as German proofreader/translator), but if I remember correctly, French was not fully finished, so there are parts missing and beside that, as ntozier mentioned, 1.9.4 is at release candidate state and should not be used for productive environments. So you will have to wait for 1.9.4 stable/final and if you like to help, join the French translation team ;)
