# valid-utf8 — Filter tool to check whether text is valid UTF-8 or not

If no file argument is given, valid-utf8 reads from standard input.

## Build

`make`

after building and installing dependencies:

- [libscstring](https://git.bobpolis.com/bob/libscstring/)

## Install

`sudo make install`

or, on OpenBSD:

`doas gmake install`

## Run

Test a file:

`valid-utf8 <file>`

No output, but exit status will be 0 on success, but 1 if file is not valid
UTF8.

Use a a filter:

`echo "some text" | valid-utf8`

Again, only exit status will indicate validity.

Find all valid UTF8 files in the current directory, and all directories under
it:

`find . -exec valid-utf8 "{}" \;`
