ID: 0058 Title: Fix email notifications containing non-ASCII characters in some situtations Component: Notifications Level: 2 Class: Bug Fix Version: 1.2.5i1 On some systems the locale C.UTF-8 was not always available. One of these is Debien Squeeze. Sending a notification email containing non-ASCII characters like german Umlauts failed in these situations. This now has been fixed by scanning all available encodings (output of locale -a) and selecting an existing UTF-8 encoding. Please make sure that at least one such encoding exists. This fix also makes sure that the output of a failed mail submission is being logged in the notification log (if you have enabled it).
