Convert the encoding of the FileReader's output to UTF-8

I am currently working on a small function that is meant to fetch the contents of an uploaded text file.

upload() {
    let reader = new FileReader();
    reader.onload = () => {
        console.log(reader.result);
    }
    reader.readAsText(this.file);
}

Everything functions perfectly when the file uploaded is encoded in UTF8, but I encounter issues with my specific case where it is encoded in UTF16_LE. This results in random spacing between characters, some characters being changed to something different, or even transformed into Chinese characters.

So, my main inquiry is how can I convert reader.result to UTF8 without the need to manually re-save the file to UTF8?

Answer №1

If you want to specify the encoding for the data returned by the FileReader.readAsText() function, you can do so using the optional encoding parameter.
