How To Enable Asian Username in Join Form?

I got this error " Only Latin Symbol allowed" please see attachment, and I run this SQL update following this thread

http://www.boonex.com/forums/topic/Dolphin-7-Can-t-support-chinese-name-.htm

but it doesn't work. Please help

Did you clear the dolphin cache after running that sql query?

• Server: Localhost via UNIX socket
• Software: MySQL
• Software version: 5.1.68-cll - MySQL Community Server (GPL)
• Protocol version: 10
• User: xxx@localhost
• Server charset: UTF-8 Unicode (utf8)

 yes, cleared all caches.

Remove the spaces.

 the spaces in the nick name or in the script? 

I would like to have spaces in the nickname also. 

Sorry, I mean the username field.  Spaces in usernames are not supported by default.  Dolphin 7.1+ can display full names (with spaces) instead of usernames from Advanced Settings in the administration panel.

Thank you all. Somehow it's working for me. I can register using Asian char and spaces. and was able to log in using it also.

Thanks
