How to get file character encoding in Node.js ?
Computer reads data in binary representation, that is why we need a way to convert text characters into binary data, this is done with the help of character encoding.
Most popular character encoding types are ASCII and Unicode. Unicode is defined as UTF-8, UTF-16, etc.
We can use a module called ‘detect-file-encoding-and-language‘ to get the character encoding of file in node.js
Syntax:
languageEncoding(pathToFile).then( fileInfo => // Do anything );
Parameters:
- pathToFile: (Relative or Absolute)Path of the actual file.
Return Value:
An Object having following values, { language: french, encoding: CP1252, confidence: 0.99 }
Setting up environment and Execution:

npm init
Step 2: Install required modules
npm install detect-file-encoding-and-language
Step 3: Create a text file
