Permitted characters in Usernames
The error message says
No space at beginning or end, at least 2 characters, must not have the following characters: \ " ' % ; ( )
BUT if you try the following
<<<brian>>> validation error
brian>test not accepted
brian<test accepted as brian
brian<>test accepted as briantest
<> Field required: Login Name (Username)
<< Field required: Login Name (Username)
>> validation error
The code is
https://github.com/joomla/joomla-cms/blob/4.1-dev/libraries/src/Table/User.php#L226-L232
So it should be matching on the < and > characters and they should be in the error message
But other parts of the validation are breaking that i think

or it should be accepted. Depends if the code is correct or the text is correct
I think the problem is not with the preg_match function
E.g- I removed the '%' character from the string and when I entered the input as '%' it was accepting it as a valid username
I tried a lot of permutations and combinations, and the problem only occurs when inputting "<>", maybe there is a problem with the clean function, because the input "<akshitrattan" is accepted but saved as "akshitrattan".

so failed message should be displayed if the user name contains < or > right?
