**Author:** `nickpj`
**Description:**
Test:
-----------------------------------------------```
curl --silent --include \
--cookie 'wikidb_session=1'\
-F 'wpName'='nickj'\
-F 'wpPassword'='^G'\
'localhost/wiki/index.php?title=Special:Userlogin&action=submitlogin'
-----------------------------------------------```
Note: "^G" is the ASCII Bell control character (
http://en.wikipedia.org/wiki/Bell_character ), not the string "^" + "G". Also
"nickj" is a valid user name on the test wiki.
Output contains this, on a wiki with error_reporting(E_ALL) :
-----------------------------------------------```
<b>Notice</b>: iconv() [<a href='function.iconv'>function.iconv</a>]: Detected
an illegal character in input string in
<b>/var/www/hosts/mediawiki/phase3/includes/User.php</b> on line <b>1798</b><br />
-----------------------------------------------```
One-line patch will be attached shortly.
