Package description
The is-utf8 npm package is a simple utility that allows you to check if a given buffer is valid UTF-8 encoded text. It is useful when you need to validate the encoding of text data in Node.js applications.
Check if a buffer is UTF-8
This feature allows you to check if a buffer contains valid UTF-8 encoded text. The code sample demonstrates reading a file into a buffer and then using is-utf8 to check if the buffer is UTF-8.
const isUtf8 = require('is-utf8');
const fs = require('fs');
const buffer = fs.readFileSync('somefile.txt');
const isValidUtf8 = isUtf8(buffer);
console.log(isValidUtf8); // outputs true or falseThis package provides a way to check if a buffer is valid UTF-8. It is similar to is-utf8 but is specifically designed for use with WebSockets where UTF-8 validation is a common requirement.
While not limited to UTF-8 validation, iconv-lite is a character encoding utility that can convert between various encodings. It can be used to check if text is UTF-8 by converting it to UTF-8 and comparing it to the original.
