isutf8 - check whether files are valid UTF-8

       Lars Wirzenius, Julien Palard

isutf8 checks whether files are syntactically valid UTF-8. Input is either files named on the command
       line, or the standard input. Notices about files with invalid UTF-8 are printed to standard output.

       If the file is valid UTF-8, the exit status is zero. If the file is not valid UTF-8, or there is some
       error, the exit status is non-zero.
