Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
isutf8 -V (return code: 1)
isutf8: unrecognized option '--version'
isutf8 --help (return code: 0)
Usage: isutf8 [-hq] [--help] [--quiet] [file ...]
Check whether input files are valid UTF-8.
This is version 1.1.
