Angular 7: How to identify the Encounter of a File?

Question

I have a function that runs when uploading files, I would like to identify the type of this Encounter. I am using the code below.

async uploadFile(event) {
    var document;
    var reader = new FileReader();
    let file = event.target.files[0];

    reader.onload = ((file: any) => {
      return (e: any) => {
        document.description = e.srcElement.result;
        document.title = title;
        document.fileName = file.name;
      }
    })(file);

    reader.readAsText(file);
  }

Any idea ?

Thank you.

You can use a library to help you: https://github.com/polygonplanet/encoding.js

If you want, you can use the definition types of this library, which is available at: https://www.npmjs.com/package/@types/encoding-Japanese

Example of use:

import * as Encoding from 'encoding-japanese';

var detected = Encoding.detect(utf8Array);
if (detected === 'UTF8') {
  console.log('Encoding is UTF-8');
}
