What are all of the things that could need to be changed about a user name?

rather than getting to an error state could we just prohibit the user from creating incomptible input in the first place with something like this? http://stackoverflow.com/questions/3199291/block-some-characters-from-being-typed-in-a-text-box

Automatically capitalize the first character when entering text in the box, strip consecutive double spaces, and ignore when there is input of invalid characters?

This is really a UX question, not design per se.

https://gerrit.wikimedia.org/r/#/c/104926/ (an under-review change) adds a warning if you choose a username that needs to be reformatted/canonicalized. For example, "my username" is changed to "My username".

It displays the warning, puts the new username ("My username") in the box, then you have to retype your password (twice), then press enter to confirm.

The main potential benefit, as I see it, is that if you don't like "My username" (the reformatted version), you can choose a different username entirely.

User experience feedback would be welcome; you can post on the change or here.
