 sanitize_file_name does not sanitize decomposed unicode characters in a
 file name when file is uploaded using Chrome and Firefox, it does work
 just fine if the file is uploaded using Safari.

 The problem probably only appears for macOS users since macOS seems to be
 the only OS storing filenames in decomposed unicode.

 Uploading räksmörgås.jpg with Safari correctly creates the file
 raksmorgas.jpg while uploading with Chrome or Firefox creates the file
 räksmörgås.jpg.
