I see for instance the welcome message in the core. If i put some content it doesn't change, i looked some codes and saw that it was indeed getting to the destination, if i changed the e-mail content everything was ok, but subjects was bogus. I saw that it was saved in mails/LANG_ISO/lang.php and then i saw the welcome message for instance, it was like: ' \'Welcome!\'' if i look in the french file it was like: Welcome! (without the space and the ') The ' is what made it bogus, i didn't know if it was when i save or when the content was retrieved, anyway the bug seems to apply only to subjects. I guess that the bug is in the retrieving of the array or in the saving names with spaces or '.
