Codex:

Sanitizes a username, stripping out unsafe characters.

Removes tags, octets, entities, and if strict is enabled, will only keep alphanumeric, _, space, ., -, @. After sanitizing, it passes the username, raw username (the username in the parameter), and the value of $strict as parameters for the {@see 'sanitize_user'} filter.
