problems with 3.1 – permalink – norwegian character

I am also looking for an answer to this problem.

If I try to add f.ex. ‘bl?b?rsyltet?y‘ to the title, I get ‘blabaersyltet?y‘ in return. I was hoping to see either ‘blaabaersyltetoey‘ or ‘bl?b?rsyltet?y‘.

Hopefully someone will be able to help us with this. Thanks.

I had the same problem, and after a lot of testing I came up with a method to rewrite ? and ? to O and o in post titles and permalinks. I don’t know how to make a plugin out of this, so as for now, we have to edit the core files.

1. Open wp-includes/formatting.php and scroll to line 655 (approx).

2. After all the decompositions, and between $string = strtr($string, $chars); and } else {, paste the following:

// Fix ? and ?
		$chars['o-in'] = array('?','?');
		$chars['o-out'] = array('O','o');
		$string = str_replace($chars['o-in'],$chars['o-out'],$string);

3. Make sure you save the file as utf-8.

Hope this helps!

(I am using WP 3.1.1)
