12194	Title tag is messed up using special characters.	Zoltan Koszegi		"We have a situation when our webpages name (this is actually the <title> tag) are tested with special character sets. As a result (loading this page into CK) the title tag completely messed up and its content is moved under the body. The title we applied is this: 
{{{
ÑÇôìë<?:""';.!@#$%^&*\)/
}}}

I could narrow down what character sequence causes the issue. So this is it: 
{{{
<?
}}}
 
So, whenever we apply this <? as a title it will be encoded and saved as 
{{{
<title>&lt;?</title>
}}}
. That is fine but during the load process this title is messed up and we get the following weird title tag:

{{{
>&lt;title data-cke-title=&quot;Rich Text Editor, Textarea1, Press ALT 0 for help
}}}

Here, there is no normal opening <title> tag and the closing </title> is missing.

Fortunately I can reproduce this kind of behavior in the DEMO. 
STR:
1. Go to DEMO page (I used IE11) and launch full featured page.
2. clear the content and switch to source view
3. paste the following string into it: (note, the <title> contains the encoded <? characters and browsers can display this title with no issue at all)

{{{
<html>
<head>
<title>&lt;?</title>
</head>
<body>
</body>
</html>

}}}
4. switch back to wysiwyg mode and the page is not empty (it should be). It contains the <? characters. This is because the <title> tag was broke up and its content moved to the body. So, something odd happens during the setData().
