title: Replace unidentified characters in xml by notepad++
body: <p>I need to find and replace all unidentified characters in an xml file using notepad++. I don't know the technical term to describe those unidentified characters, probably they cant even be called characters, so i'm attaching an example image:</p>
  
  <p><a href="https://i.stack.imgur.com/vYyvs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vYyvs.png" alt="example case"></a></p>
  
  <p>The stuff between "string" and "/string" is what i need to find. You know: they can't be copied like text because they're not actually text and if i try to copy it here it looks like this:</p>
  
  <p>So how do i find all of them (excluding newlines) and clear (replace with "blank") from the file by using regex?</p>
  
  <p>edit: Encoding >> Convert to UTF-8 does not clear those</p>
  
  <p>edit: I uploaded a sample file to better illustrate the situation here: <a href="https://file.io/QsyodE" rel="nofollow noreferrer">https://file.io/QsyodE</a> : I need to weed out the unidentified stuff like the ones in "Genre" strings, the ones before the kanji(?) characters. You can't see those stuff if you open the file with a pure text viewer (like notepad) because they are not actually text (and that is why I need to remove them because the fact that they are not text make the original humongous XML file unimportable by iTunes); but you see them when you open it with Notepad++.</p>
