Is there a way to retrieve and encode .woff files without any corruption?

Question

I am attempting to retrieve a .woff font file from a url, convert the bytes to hex and then store the file in the new encoded format.

Currently, I have a function which does just this however the file somehow get's corrupted somewhere inbetween.

The function which I have currently is as following:

function getfont(url) {
    fetch(url).then(function(response) {
        return response.text();
    }).then(function(text) {
        var hex = [];
        for (var i = 0; i < text.length; i++) {
            hex.push(text.charCodeAt(i).toString(16));
        }
        console.log(hex.join(''))
    })
}

I have checked the response before encoding and do not seem to see anything obvious which clues me to how the file is getting corrupted after it is being encoded and I have also checked that the font stored at the url works beforehand.

How would I go about fetching the .woff file and storing it as an encoded string without any corruption and being able to use the file after decoding it?
