# isutf8

> Check whether text files contain valid UTF-8.
> More information: <https://manned.org/isutf8>.

- Check whether the specified files contain valid UTF-8:

`isutf8 {{path/to/file1 path/to/file2 ...}}`

- Print errors using multiple lines:

`isutf8 {{[-v|--verbose]}} {{path/to/file1 path/to/file2 ...}}`

- Do not print anything to `stdout`, indicate the result merely with the exit code:

`isutf8 {{[-q|--quiet]}} {{path/to/file1 path/to/file2 ...}}`

- Only print the names of the files containing invalid UTF-8:

`isutf8 {{[-l|--list]}} {{path/to/file1 path/to/file2 ...}}`

- Same as `--list` but inverted, i.e., only print the names of the files containing valid UTF-8:

`isutf8 {{[-i|--invert]}} {{path/to/file1 path/to/file2 ...}}`
