11690	Placeholder with forbidden characters	Piotr Jasiun		"1. Open placeholder sample (plugins/placeholder/samples/placeholder.html).
2. In the source mode enter:
{{{
<p>This is a [[sample ]placeholder]].</p>
}}}
3. Switch back to the WYSIWYG mode.

'''Result''': there is no placeholder.

4. In the source mode enter:
{{{
<p>This is a [[sample >placeholder]].</p>
}}} 
5. Switch back to the WYSIWYG mode.

'''Result''': there is a placeholder.

6. Open placeholder dialog.
7. Press ""Ok"".

'''Result''': Error message:

   The placeholder can not be empty and can not contain any of following characters: [, ], <, >

--------------------------------------------------------------

On the one hand it is not possible to upcast placeholder with ']' character, because it is forbidden, but on the other we can do it with '>'.

In my opinion it should not be possible to upcast placeholder with forbidden character but also it would be good if user would be informed that the placeholder contains forbidden character."	Bug	confirmed	Normal		General	4.3
