Nani?

You can actually leave out the '80 <', since failing the first condition automatically rules that out.

I never would have thought to use the set like that. Very clever!

Eva is actually closer to the original Hebrew.

Strings are immutable in Go. So if you append to a string, what it has to create a whole new string every time. String builder on the other hand is mutable, so it's going to be more memory efficient.

Oh, I didn't know about control code. Thanks for clarifying. Well, I don't know what's best to do here though. Maybe just accept both (since this is just a 7kyu kata, which leans more towards beginners and they shouldn't worry about ASCII and stuff like that)?

Yes, its because 2 is a control code, which Go seems to drop when appending to a string. If its a problem, I can adjust the random test generator to accept both anwsers.

Hmmm, for the input >( >:C >:C >( :D :) :), when I tried to use this operation for the result:

func Deemojify(emote_string string) string {
  // ...
  res := ""

  for ... {
    // ...
    res += string(byte(i)) // i is an integer
  }

  return res
}

It gives the following error:

Expected
    <string>: é\x02d
to equal
    <string>: \xe9\x02d

But if I change res to array of bytes, append the byte on each loop, and convert it in the end, it matches correctly. Is this normal/expected?
