Umlaut in member name

    • Posted 2 years ago #

    Hi, when I have an umlaut in a membername it gives me this sign: �

    Example: If there is a member with the name "Müller" it shows "M�ller".

    How can I replace that � sign with the correct umlaut?

    umlauts: ä, ö, ü

    Strange is that this problem occurs only with member names. In the forum posts the umlauts are displayed correctly.

    I use wordpress integration...in wordpress the member names are displayed correctly. Only in bbpress the umlauts are not displayed correctly in the member names.

    That sounds like an old problem with integration. Can't find the thread right now though.

    I looked a bit around and found a peace of code with which I was able to create a plugin.

    <?php
    /*
    Plugin Name: UTF-8 usernames
    Description: This plugin enables utf-8 characters in usernames. Mbstring must be enabled in the php.ini.
    */

    function sanitize_user_mbstring( $raw_username, $username, $strict = false ) {
    $raw_username = $username;
    $username = strip_tags($username);
    // Kill octets
    $username = preg_replace('|%([a-fA-F0-9][a-fA-F0-9])|', '', $username);
    $username = preg_replace('/&.+?;/', '', $username); // Kill entities

    // Usage of 'mb_ereg_replace' instead of 'preg_replace' to preserve accents.
    if ( $strict )
    $username = mb_ereg_replace('|[^a-z0-9 _.\-@]|i', '', $username);

    return apply_filters('sanitize_user_mbstring', $username, $raw_username, $strict);

    }

    add_action('sanitize_user', 'sanitize_user_mbstring', 0, 3);
    ?>

    Unfortunately it doesn't work properly. When it displays correctly in bbpress it doesn't in wordpress and reverse. I don't have access to the php.ini. Could it be, that the thing with "mbstring" is the problem?

    Ensure that your forum's encoding is utf-8

    I have in both...UTF-8 but it doesn't work.

    I solved the problem by adding the following additional code to the plugin:

    add_filter( 'get_user_display_name', 'rk_display_name' );
    function rk_display_name($name, $ID = 0) {
    if ( !seems_utf8( $name ) )
    return utf8_encode( $name );
    return $name;
    }

    We needed to add another filter, so the code looks like this:


    add_filter( 'get_user_display_name', 'rk_display_name' );
    add_filter( 'get_post_author', 'rk_display_name' );

    function rk_display_name($name, $ID = 0) {
    if ( !seems_utf8( $name ) ) {
    return utf8_encode( $name );
    }
    return $name;
    }
