jschardet is a JavaScript library for character encoding detection. It is a port of the Python chardet library and is used to detect the character encoding of a given text. This can be particularly useful when dealing with text data from various sources where the encoding is unknown.
Detect Character Encoding
This feature allows you to detect the character encoding of a given text. The `detect` method returns an object with the encoding and confidence level.
const jschardet = require('jschardet');
const text = 'Some text with unknown encoding';
const result = jschardet.detect(text);
console.log(result);chardet is a character encoding detection library for Node.js. It is also a port of the Python chardet library and offers similar functionality to jschardet. While jschardet is written in JavaScript, chardet is written in C++ and may offer better performance in some cases.
iconv-lite is a character encoding conversion library for Node.js. While its primary focus is on converting text from one encoding to another, it also includes some basic encoding detection capabilities. It is more versatile than jschardet in terms of encoding conversion but may not be as specialized in detection.
node-icu-charset-detector is a Node.js binding for the ICU (International Components for Unicode) library's charset detection functionality. It provides robust and accurate character encoding detection, leveraging the power of the ICU library. It is more heavyweight compared to jschardet but offers high accuracy.
Port of python's chardet (http://chardet.feedparser.org/).
LGPL
npm install jschardet
var jschardet = require("jschardet")
// "àíàçã" in UTF-8
jschardet.detect("\xc3\xa0\xc3\xad\xc3\xa0\xc3\xa7\xc3\xa3")
// { encoding: "UTF-8", confidence: 0.9690625 }
// "次常用國字標準字體表" in Big5
jschardet.detect("\xa6\xb8\xb1\x60\xa5\xce\xb0\xea\xa6\x72\xbc\xd0\xb7\xc7\xa6\x72\xc5\xe9\xaa\xed")
// { encoding: "Big5", confidence: 0.99 }
// See all information related to the confidence levels of each encoding.
// This is useful to see why you're not getting the expected encoding.
jschardet.Constants._debug = true;
// Default minimum accepted confidence level is 0.20 but sometimes this is not
// enough, specially when dealing with files mostly with numbers.
// To change this to 0 to always get something or any other value that can
// work for you.
jschardet.Constants.MINIMUM_THRESHOLD = 0;
I haven't been able to create tests to correctly detect:
