title: Notepad++ showing null values after crash
body: <p>I was editing a files in Notepad++ which I saved. Unfortunately I did not close Notepad++ application and PC was powered down due to out of battery. 
  When the power was back on, I opened my file and found only <code>'nul' 'nul' 'nul' 'nul' 'nul'</code> all over doc.This was a text file i was working on saving xml code in it. However my file is of size 300kb. And the size of 'nul's added is to the same size as the previous length of the document. I tried everything there is no cache copy of this saved also by notepad++, is there any way to fix this?</p>
