<![CDATA[ For those reading this on 2021.
I'm creating a multisite on WordPress 5.6 and I could allow hyphenated usernames by changing the following on the original wpmu_validate_user_signup function in wp-includes/ms-functions.php:
<code>
function wpmu_validate_user_signup( $user_name, $user_email ) {
...
if ( $user_name != $orig_username || preg_match( '/[^-_a-z0-9]/', $user_name ) ) {
$errors->add( 'user_name', __( 'Usernames can only contain lowercase letters (a-z), -, _ and numbers.' ) );
$user_name = $orig_username;
}
...
}
</code>
Just change the regular expression to be: /[^<b>-_</b>a-z0-9]/ ]]>

Didn't try it cause I'm kinda newie working with WordPress, but I'm going to do a research and change code correspondingly. It makes sense what you say that the WordPress core may be changed in coming versions and thus the changed functionality. Thanks for the tip! ;) ]]>

It isn’t really safe to change code in wp-includes as Wordpress may update core code automatically at any time. Also it might not be possible for people running managed installations.
The safest way to modify behaviour is via hooks - does the hook not work in 5.6? ]]>

<![CDATA[ Just wanted to note: Still works fine, as soon as you change the translated text to the new wording in https://core.trac.wordpress.org/browser/tags/4.8/src/wp-includes/ms-functions.php#L420, which is:
__( 'Usernames can only contain lowercase letters (a-z) and numbers.' )
Thanks,
