What should I do if the WordPress Chinese characters user name cannot be registered ?, Wordpress Chinese Characters

WordPressRegistered users do not support Chinese characters. However, Chinese registration is required in the project recently.

Later I thought of a simple solution:

Open wp-nodes des/formatting. php and find

Function sanitize_user ($ username, $ strict = false ){

Set $ strict to false, that is, add the following code to the next line of the sanitize_user function:

$ Strict = false;

Or comment out

// $ Username = preg_replace ('| [^ a-z0-9 _. \-@] | I', '', $ username );

So everything is OK!

However, it should be noted that the same processing needs to be done during the next upgrade.
