If a RSS feed item has a µ in it's title it will be added to the messagelist on every update.

Reproducible: Always

Steps to Reproduce:
1. Find a RSS feed with a message with a µ in the title.
2. Request the messages from this feed.
3. Add a new message to the RSS file.
4. Request the messages from this feed again.

Actual Results:  
Although this should actually result in 2 of the same, this is the result after a day or 2: http://www.progamestudios.com/web/%B5bug.png

Expected Results:  
It should have displayed the message only once instead of -as much as updated-.

This problem did occur earlier on the same feed, with about the same message (about µTorrent).

The feed in question is http://feeds.feedburner.com/tweakers/mixed

<description>Vandaag is er een nieuwe bètarelease van µTorrent uitgekomen. µTorrent is een BitTorrent-client met een lage geheugen- en processorbelasting, waarbij de grootte van het programma zelf ook nog eens minimaal is.

Thanks for the great report. Unfortunately, this is a duplicate of a long-standing neglected bug. :(

ah sorry, I couldn't find the bug report. I hope it will be fixed in the next release.

note that I only get this bug on this specific feed message. Like stated in this bug report I got this problem once more (I am using thunderbird for over a year now). With a very similar message form the same feed about µTorrent. I know it's speculation but I bet the duplicate check breaks on the µ in this case.

There are some other duplications but those are not as severe as this one.
