The RSS generator uses "mysql2date" function for the pubDate-tag. This function is also used in single.php of the Kubrick-theme. My german localization translates the $weekday and $weekday_abbreviation so that the weekdays appear in German. Like this, the RSS genereator produces something like
<pubDate>Do, 03 Mar 2005 23:05:05 +0100</pubDate> though it should be
<pubDate>Thu, 03...</pubDate> so the feed is not valid . Shouldn't the RSS generator use some more generic weekdays description which is not translatable?
