How to convert ASCII string to UTF-8 in javascript

Question

I need to convert an ASCII string to UTF-8 with javascript.

So the following raw ASCII strings:

imagￃﾨ-thrￃﾩￃﾪ.png
imￃﾤge-twￃﾶ.png
ￃﾬmￃﾡgￃﾩ-fￃﾲￃﾻr.png

Needs to be converted to:

imäge-twö.png
imagè-thréê.png
ìmágé-fòûr.png

I can do it with this online utility (so it's possible!). Looking for a way to do it with a javascript function.

In Node.js: Buffer.from(text, 'ascii').toString()

You can actually use this utf-8 library for that. If you are using plain javaScript you need to save the utf-8.js file and use it in <script src=""> tag. Then you can useutf8.decode() function. Something like:

<body>
    <script src="./utf-8.js"></script>
    <script>
        console.log(utf8.decode('imagￃﾨ-thrￃﾩￃﾪ.png'))
        console.log(utf8.decode('imￃﾤge-twￃﾶ.png'))
        console.log(utf8.decode('ￃﾬmￃﾡgￃﾩ-fￃﾲￃﾻr.png'))
    </script>
</body>
