This is great, but they’ve really missed an opportunity to go over 9000 here.

I wonder if there are downsides hiding in unicode/emoji features like combining characters and punycode that may “break” output or otherwise confound the copy/paste behavior needed for the return trip.
That’s a good question; for instance, are nonbreakable spaces …breakable? But emoji-land is avoided as emojis go from U+10000 to U+1FFFF, and this rotates chars U+0 through U+FFFF; given the U+8000 middle point (“We meet at midnight” ain’t gonna end up: 
)

rot26 is what I use; twice as secure as rot13!

Alas, I suppose rotBEEF just isn’t feasible.

I rot13 twice for extra security.

They would have been better off using the emoji codepage here.
That being said, nothing beats 4 pass rot13 for the ultimate in encryption.

The screenshot intrigued me - looks like kanji right there. So why not test this…:
Then let’s hit up Google Translate…
Well. That was interesting

There’s Chinese characters there but it’s a coincidence due to how Unicode character ranges work. It’s all gibberish.
