It completes successfully, exit status is 0. You can easily create such a
file and reproduce this: just open vi(1), set the encoding with
`:se fe=iso-8859-1', and just type a letter with an accent, like:
If you save it and reopen it with vi(1), it will use UTF-8 by default and it
won't be able to read the line with `ì', unless you again use
The correctness (and integrity) of the ISO 8859-1 encoding is also shown by
$ hexdump -C myfile
00000000 68 65 6c 6c 6f 0a ec 0a |hello...|
Where `ec' is `ì' in ISO 8859-1.
