How to obfuscate javascript this way

Hi,

I wonder if there anyway I can get my javascript codes obfuscated in foreign characters like in the link below:

Thanks

The web page at http://synth.bitsnbites.eu/ gives you instructions on how it was obfuscated.
You will find those instructions at the part of the page that says: “The program was compressed using”

Thank you,

That’s very helpful.
