# isutf8
> Check whether text files contain valid UTF-8.

- Check whether the specified files contain valid UTF-8:
`isutf8 {{path/to/file1 path/to/file2 ...}}`
- Print errors using multiple lines:
`isutf8 --verbose {{path/to/file1 path/to/file2 ...}}`
- Do not print anything to `stdout`, indicate the result merely with the exit code:
`isutf8 --quiet {{path/to/file1 path/to/file2 ...}}`
- Only print the names of the files containing invalid UTF-8:
`isutf8 --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 --invert {{path/to/file1 path/to/file2 ...}}`
