## DESCRIPTION

`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.

## OPTIONS

`-h`

`--help`

- Print out a help summary.

`-q`

`--quiet`

- Don't print messages telling which files are invalid UTF-8, merely indicate it with the exit status.

`-l`

`--list`

- Print only the names of files containing invalid UTF-8.

`-i`

`--invert`

- Invert the selection: list UTF-8 compatible files.

`-v`

`--verbose`

- Also print an hexdump-like view of the error and some context.

## EXIT STATUS

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.
