File handles expect bytes by default.

You're providing Unicode Code Points.

Converting text to bytes is called encoding. You told the other end you were providing UTF-8, but you never applied this encoding.

But what is the difference between ":encoding(UTF-8)" and ":utf8"?

`:encoding(UTF-8)` vs `:encoding(utf8)` vs `:utf8`
