I have a website in German. We have a lot of people subscribed to the website (around 2000).
Since one of the latest updates it is not possible for people to login when they have a login name with Umlaute like "Götze", "Müller".

Core only supports strict ASCII usernames, see #5918.

When I try to register as "Götze" on a clean install, I get an error: "This username is invalid because it uses illegal characters. Please enter a valid username."

sanitize_user() function is used for validation: tags/3.6/wp-includes/formatting.php#L885.

The last two changes there were [14428] and [15948], in WordPress 3.0 and 3.1.

Did you use a plugin to allow those usernames?

The login always worked till I updated yesterday to 3.6

We have a programmed a special registration page and insert the user directly in the database.
