Repair for redlinks patch

The redlinks patch uses a callable in the form of array( $obj, 'method' ).
This type of callable is not directly invokable and must be called via
call_user_func or call_user_func_array.

Additionally the decision to convert or not convert utf-8 -> html entities
must be delegated to the caller, or be made smarter.
