What is codepage?

The codepage npm package is a library for converting data between different character encodings. It supports a wide range of code pages and provides functionality for encoding and decoding text.

What are codepage's main functionalities?

Encoding Conversion

Convert strings between different encodings. In this example, we convert a binary string to UTF-8 and vice versa using code page 437.

var cp = require('codepage');
var utf8String = cp.utils.decode(437, Buffer.from('Hello World', 'binary'));
var binaryString = cp.utils.encode(437, 'Hello World');

Stream Transformation

Create a stream that transforms data from one encoding to another. Here, we create a transform stream that encodes incoming data to code page 437.

var cp = require('codepage');
var stream = require('stream');
var converter = new stream.Transform();
converter._transform = function(chunk, encoding, done) {
  this.push(cp.utils.encode(437, chunk.toString()));
done();
};

Handling Code Pages

Access information about different code pages. This code sample retrieves information about code page 437.

var cp = require('codepage');
var cpInfo = cp[437];
console.log(cpInfo.name);
