Permalink with Norwegian/Danish character 'ø'

[knutsp]

When a post title contains the 'ø' character, the post name and permalink is created without removing this character. The result is that the permalink in such cases are broken (not found).

Permalinks are set to /%year%/%monthnum%/%postname%/ and the server is IIS7 with rewrite module. Tested on 3.1-RC2-17283.

It seems there was a typo in remove_accents() which made the same character be checked twice.

This is not a regression - bug is very old

Moving to Future Release.

On Apache, in my testing, it doesn't 404, however the accented character does slip into the slug as urlencoded.

The attached patch fixes it and corrects it to o as expected for me.

[scribu]

Yes, it would have triggered 404s for old posts, if it weren't for [15929].

Shouldn't the milestone for this be 3.2? I see a keyword 3.2-early.

Lots of tickets were marked for 3.2 that were not actually slated for the milestone. Unfortunately, some code we were considering for better permalink sanitization did not make feature scope. Hoping for 3.3.

This is a pretty obvious typo though, so I can support it for 3.2.

@nacin: May I still hope for 3.2?
