isutf8

Check whether text files contain valid UTF-8. More information: https://joeyh.name/code/moreutils/.

• 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 …
