Description Antoine "hashar" Musso (WMF) 2013-03-25 09:52:44 UTC 
The 'Æ' is a letter and is currently normalized differently. The upper case form is normalized to 'AE', the lower case to 'A'.
Comment 1 Antoine "hashar" Musso (WMF) 2013-03-25 10:09:18 UTC 
The root cause is the equivalence file on our wiki: http://www.mediawiki.org/wiki/AntiSpoof/Equivalence_sets which is then copied under maintenance/equivset.in.

The file list uses the format:
 <hexadecimal codepoint> <character> => [<hexadecimal codepoint>] <character>

The relevant part:

E6 æ => C6 Æ
E6 æ => 41 A
4D4 Ӕ => C6 Æ
4D5 ӕ => C6 Æ

Running maintenance/generateEquivset.php generates a PHP array of the list which uses the character for key.  The codepoint E6 has two entries, I guess only the second one is taken in account.
Comment 2 Antoine "hashar" Musso (WMF) 2013-03-25 10:11:06 UTC 
I have removed the always failing test with https://gerrit.wikimedia.org/r/#/c/55553/
