title: How to remove invisible line break character
body: <p>I have big data at excel, and some cells contains html codes. These cells have line breaks in them. I tried to replace line breaks (Alt+010, \n) but excel said there is no char like this. 
  When I copied cell to notepad, there is no line break. 
  When I copied from notepad to phpmyadmin sql area or textpad, I see line breaks again. 
  There are notepad, textpad and phpmyadmin sql area screenshots below. How can I remove these invisible line breaks?
