[wp-hackers] get_tag alphabetical sorting not working correctly in Danish

[Lisa Risager]

We have 3 special characters in Danish: æ, ø and å.

When using get_tag the letters æ and ø sorts alphabetically, but å is
placed before a in the alphabet (should be the last letter).

I'm using this code:
$tags = get_tags();
$html = '<div class="post_tags">';
foreach ($tags as $tag){
$tag_link = get_tag_link($tag->term_id);
 $html .= "<li><a href='{$tag_link}' title='{$tag->name} Tag'
class='{$tag->slug}'>";
 $html .= "{$tag->name}</a></li>";
}
$html .= '</div>';
echo $html;

from http://codex.wordpress.org/Function_Reference/get_tags

which works fine except for the alphabetical sorting of the letter å.

I am using WordPress 3.3 da_DK

There's a trac for french accents:

Anyone who can point me in the right direction for hacking this bug?
