New description:

 When the page slug is generated from the post title, three icelandic
 letters are not converted correctly. These three letters are Ð ð, Þ þ and
 Æ æ. They should be converted to D d, TH th and AE ae but are not.

 For instance, when I made a post with the title ‘Þátturinn’ the post-slug
 would become ‘þatturinn’ and when I tried to enter that address in my
 address bar it changed to ‘%c3%beatturinn’ and I got a ‘page not found’
 error from Wordpress.

 This can be fixed by adding the following six lines to formatting.txt, in
 the function remove_accents, inside the '''if (seems_utf8($string)) {'''
 condition.

 {{{
 chr(195).chr(144) => 'D',
 chr(195).chr(176) => 'd',
 chr(195).chr(158) => 'TH',
 chr(195).chr(190) => 'th',
 chr(195).chr(134) => 'AE',
 chr(195).chr(166) => 'ae',
 }}}

 Also (from #5952)
 When the post slug is generated from the post title, the letter 'Å' 'å'
 converts to 'a', should convert to 'aa' which is the general practice in
 countries using this character (Confer
 [http://en.wikipedia.org/wiki/%C3%85#Transcription Wikipedia]).

 Furthermore, the Norwegian/Danish characters 'Æ' 'æ' and 'Ø' 'ø' should be
 converted to respectively 'ae' and 'oe'. As of now, these convert to
 '%c3%a6' and '%c3%b8'.

Comment:

 Closed #5952 as a dupe of this and updated bug with more characters to
 fix.

 Moving to 2.6 as this needs fixing early and lots of testing so we can be
 sure we don't break things.
