Problem User Registration with german äöü

hello,
i have installed rc1. It works good, but i have a problem with user registration with usernames include äöü.
E.g username ist "allgäuerpeter", registration and backlink are ok. Account is active,but the user cannot log in.
Note, in the mail the username is: allgÃ¤uerpeter. But also with username "allgÃ¤uerpeter" i cannot log in.

What can i do?

Thanks
Andreas

Hi,

I just tested to register a user with special characters on this forum and everything seems to be fine (see here).

:confused:

Hello Alex,

Hello Andreas,
i had the same problem, i think there is something wrong with the coding of the characters. I use UTF-8 on all sites of my Homepage, but the Mail has in the "to" Field the Wrong characters and in the Text body everything is OK.
When I'm make the Same thing in this Forum the characters are in both String OK.
I think something on my Server is in ISO-8859-1. I must search.

Ok,
now I found something.
In UTF-8 a small ö and a strtolower(ö) is not the same, that is the Problem.
In the login.inc.php on row 74 there is a MySQL SELECT statement,
...WHERE lower(user_name) = '".mysql_real_escape_string(strtolower($request_username))..., that is the cause of the Problem.

But I don't understand why in this Forum it is no Problem to Register Usernames with äöüß.

I am hopeful we can find out a solution.
