CCP, the developer of Eve Online, has a nice way of showing their intelligence. They recently added (proper) localization support to their game, which is nice for our russian and other non-latin friends. As a side-effect however they included localization of killmails, which horribly breaks importing them to any killboard. Many killboards have been updated (read: work around ccp's fail), but you're the one stuck posting to a killboard that hasn't been updated.
That's where KillmailUnfucker comes to help. It monitors your clipboard for any killmails you may have copied from the Eve Online combat log. When it detects you copied a killmail that is malformed, it fixes it and updates the clipboard.
