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 ...}}
