The content type name 'linkoblast' cannot contain: \ / : * ? " # % < > { } | ~ & , two consecutive periods (..), or special characters such as a tab.

I was developing a content type in SharePoint 2010. Everything was good till I entered details in my Form. But it went wrong after I pressed "Create" button.

I got a strange error message as displayed below:

Microsoft.SharePoint.SPInvalidContentTypeNameException: The content type name 'Linkoblast\AddressBook' cannot contain: \  / : * ? " # % &amp;amp;lt; &amp;amp;gt; { } | ~ &amp;amp;amp; , two consecutive periods (..), or special characters such as a tab.
