chardet

Chardet is a character detection module for NodeJS written in pure Javascript. Module is based on ICU project http://site.icu-project.org/, which uses character occurency analysis to determine the most probable encoding.

Installation

npm i chardet

Usage

var chardet = require('chardet');
chardet.detect(new Buffer('hello there!'));
// or
chardet.detectFile('/path/to/file', function(err, encoding) {});
// or
chardet.detectFileSync('/path/to/file');

Working with large data sets

Sometimes, when data set is huge and you want to optimize performace (in tradeoff of less accuracy), you can sample only first N bytes of the buffer:

chardet.detectFile('/path/to/file', { sampleSize: 32 }, function(err, encoding) {});
