Crash on API16 for titles containing % character

[oguzkocer]

I am guessing the following crash happens due to the deprecated methods getting called with the new parameter. I don't think this should normally happen, but it's still a good idea to update the deprecated methods.

/cc @aforcier because I don't know who works on this editor anymore.

Fatal Exception: java.lang.IllegalArgumentException: Invalid % sequence at 187: callback-response-string:function=getHTMLForCallback~id=zss_field_title~contents=Ripped-off Britons: Democracy puts strength in the hands of the many. Why in democratic Britain are the 90% treated like cattle for milking and for eating?

I don't think the deprecated methods are the cause - from the crash reports, this is only happening on API 16. It looks like an HTML encoding issue.
