title: Line feed regular expression doesn't work in Geany
body: <p>I want to detect line feed with <a href="https://www.geany.org/" rel="nofollow noreferrer">Geany</a> in Ubuntu. I used regular expressions such as <code>\n</code> , <code>\r</code> and <code>\r\n</code>, but it doesn't detect anything.</p>

  <p>There are some line ending settings that I also try to change to make it work, but still no success:</p>

  <p>And finally, I also tried to use different encoding from document → set encoding menu, but still no success.</p>
  <p>I guess I am doing something wrong, but I still don't know what.</p>
