[silu44]

Dear Sir

i translated buddypress to arabic and i want my members to use arabic user names

it works fine but on : when viewing user profile page this field( @usename in arabic ) return strange characters.

Hello @silu44

Please can you give me a sample Arabic username that causes this problem? It will help us check the bug. Thanks.

Hi DjPaul

for example this user name ( رماح )

[silu44]

here is the code that print the user name :

<span class="user-nicename">@<?php bp_displayed_user_username(); ?></span>

@silu44

How did you *register* a user name of "رماح" in WordPress?

When I try adding a user through /wp-admin/user-new.php, it won't create the user account.

@DJPaul i'm using :

Buddypress + Wordpress Special Characters in Usernames + Paid Memberships Pro

those are the plugins related to my post ,

It looks like we need to run urldecode() on the mention name function.

I'm proposing we add the filter needed to make this work, and then a 3rd-party plugin can run the urldecode() function on this filter:

add_filter( 'bp_activity_get_user_mentionname', 'urldecode' );

Edit: This will fix the mention name display, but we would probably need to fix bp_activity_find_mentions() so it checks url-encoded values as well.

Maaaybe. We can add a filter, sure, but I think would probably want more unit tests to ensure everything's consistent with the parsing and display of these.

At any rate, since the Special Character plugin allows different characters in the username/nicename, I'm tempted to suggest the best quickest fix is to enable BP_ENABLE_USERNAME_COMPATIBILITY_MODE where we already handle URL decoding.

Good point. We (or a plugin) would still need to apply urldecode() to various spots that generate a user profile URL so the member profile will resolve properly:
add_filter( 'bp_get_member_permalink', 'urldecode' );

Needs further auditing.

[silu44]

nothing of the mentioned solutions solved the problem.

silu44 - For now, you can add the following to ​wp-content/plugins/bp-custom.php:

// Enable username compatibility
define( 'BP_ENABLE_USERNAME_COMPATIBILITY_MODE', true );

// URL decode member permalinks on the Members Directory page
add_filter( 'bp_get_member_permalink', 'urldecode' );

This probably will not solve 100% of the issues, but it should get you partially there. If you do encounter other bugs, please let us know.

thanks @r-a-y it works fine for me, everything is good now .

i can register with arabic username and nicename
i can view user profile normaly
user permalink is fine .

1-just the user with arabic name not showing up on ( members page or search result )

on localhost it works good , but online not working :
2-when trying to activate user account it say ( can't activate "username" - the sign-up has already been activated. ) and user deleted

Going to reopen this.

I think if BP_ENABLE_USERNAME_COMPATIBILITY_MODE is set to true, we should automatically add various filters like the 'bp_get_member_permalink' filter and fix up various things like the activation issue as stated in comment:11.

I'll try and look into these things in 2.5.
