I am the person who wrote that encoder you link to at https://www.proles.net/emailencoder/. I have written a new and improved site, https://www.addressmunger.com . It still has the old encoder, and it can now also encode your email address into a javascript function for the (slightly) more advanced users. I would greatly appreciate it if you would update your link.
Thanks,
