Description of problem: Using Safari 1.2 (v125) on OS X. If I enter a "ø" (ø htmlencoded) in the name field, it gets returned as the unicode character, but apparently not with the correct http headers. How reproducible: Always. I put a screenshot at http://x1.develooper.com/~ask/tmp/rhnbug.png
Red Hat currently only views a subset of the ascii character set as valid for usernames. First & last names should be safe at this point. Please re-open this bug if you're continuing to have issues.
