Clicking on member names with spaces returns error

Wellwisher

Clicking on member names with 'spaces' returns the following error:

"The page you requested could not be found."

Error in console shows as:
Failed to load resource: the server responded with a status of 404 ()

I noticed if I have usernames with spaces, I can't seem to click on their usernames?
I think this is because my forum is a migration from SimpleMachines forum, where it allowed spaces?

Also @mention does not work for usernames with spaces in their name

Example URL: 

tinyurl.com/39vrya92

I was able to access the member with spaces by changing the naming slug to ID (as shown in the image below).
But the @mention is still not working for such usernames. I think the only way to fix it is to manually change the username to remove spaces and emailing the member about their username:

Please mark as solved - it's not a Flarum issue. It's worth having this thread for anyone who's migrated.

If your previous forum (that you migrated) has member names with special characters, periods or spaces, be sure to correct later.

The username column of Flarum only officially supports alpha-numerical ASCII characters, dashes, and underscores.

MySQL will not prevent storing other characters though, and most Flarum features will probably work fine even with unexpected characters. However the Mentions extension relies on regular expressions which have been optimized for the default set of allowed characters. The username URL slug driver is another one, since it's not expecting other characters it's not encoding them for use in an URL.

If you really want more advanced username formatting, the intended solution is to use Nicknames which aren't unique or part of any URL and therefore not restricted to any particular character.

I don't think there's any public extension for this, but the next part would be to hide usernames completely and fill them with a random unique value automatically if you are not using them for URL slugging or legacy mentions. I implemented this manually on a forum where people only interact using their email. It might be a bit difficult to make a universal extension that works for all use cases.
