Well, as you know already, the correct datatype for the username should
be varchar. And after that you have to correct the values in the
columns, trimming the spaces at the end: 'peter ' is the same in
varchar() and in char(); it's 'peter' that's different, because char()
appends spaces at insertion time.
I think you can correct them with
UPDATE users SET username=trim(username)
