BuddyPress.org

Using WordPress 3.8 and BuddyPress 1.9

After upgrade to BP 1.9, the message usernames auto-complete functionality stop working properly.

In my install I allow Arabic characters in usernames using sanitize_user filter, and allowing BP username compatibility mode:

add_filter('bp_is_username_compatibility_mode', '__return_true');

The problem is when start typing a name in Arabic, the menu will show the encoded username, something like this:

(%D8%B3%D8%A7%D9%85%D8%B1)

while in previous version is showed the name correctly, like:

(سامر)

and when clicking on the name it will not choose it as before, instead I get error in console (firebug console):

Error: Syntax error, unrecognized expression: #un-%D8%B3%D8%A7%D9%85%D8%B1

I am using child theme of bp-default theme, and the problem caused by line 986 on bp-default/_inc/ajax.php where urlencode is applied to usernames

$username = urlencode( $ud->user_login );

I think this will apply to all non-English (and non-Latin?) characters if allowed in WP usernames.
I am aware I can fix that in my case by overriding bp_dtheme_setup() function and include my own copy of ajax.php file which will not apply urlencode to usernames, but I really don’t want to do that and wish to continue using parent ajax.php.

Thanks.
