title: Umlauts in filenames are replaced with dots
body: <p>So a user tried to uplaod some files with umlauts in the filename to my system (the system is running apache2 with laravel acting as the framework). What the script does is it uploads the files to the server and saves an entry in the DB (the encoding is utf8_general_ci).But when he tries to download the files he gets an "file not found" error. I looked at it and the files have been uploaded correctly to the server.When I downloaded them and looked at the filenames in the console they appear likes this:</p>
  
  <p><a href="https://i.stack.imgur.com/IuRBq.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IuRBq.jpg" alt="See screenshot"></a></p>
  
  <p>You will notice that the last file is shown correctly. I tried renaming it and I just replaced the umlaut letter with the same letter and that fixed it.Do you know what the problem might be?</p>
