If this file is opened with a text editor that assumes the input is [[UTF-8]], the first and third bytes are valid UTF-8 encodings of [[ASCII]], but the second byte (<code>0xFC</code>) is not valid in UTF-8. The text editor could replace this byte with the replacement character to produce a valid string of Unicode [[code point]]s for display, so the user sees "f�r".
