WordPress Special Characters in Usernames


This plugin enables usernames containing special characters (russian, cyrillic, arabic …) on your WordPress blog.

Per default WordPress does not allow to use special characters in usernames. Non-latin characters are silently filtered out and your users cannot create accounts containing cyrillic (russian) or arabic letters. This plugin is the solution to this problem.

The plugin works for users that register with their username/password as well as for users that register using our Social Login plugin for WordPress.

Please Note
Special characters are encoded in the database and take a bit more space than regular characters.

If users having special characters in their usernames still cannot register after having installed the plugin then you probably have to increase the length of the column user_nicename in the table wp_users in your database.


ALTER TABLE `wp_users` CHANGE `user_nicename` `user_nicename` VARCHAR(255) NOT NULL DEFAULT '';


  1. Upload the plugin folder to the ‘/wp-content/plugins/’ directory of your WordPress site,
  2. Activate the plugin through the ‘Plugins’ menu in WordPress,

Had to edit my wp DB to increase length of user_nicename. Totally worth it.
