Learning Erlang after Elixir
I’m planning to learn Erlang. I’ve seen forum answers that Erlang and Elixir are quite the same. After learning Elixir, in what part of Erlang should I start learning given that I learned Elixir. And if I should avoid some parts of Erlang that are already in Elixir to avoid redundancy. (if there are)

The erlang :string module is now UTF-8 aware. Generally speaking the erlang syntax is simpler with very few “special cases” and basically only one way of writing things.

Yes. It now also works on binary strings as well list strings and and on combinations of both. It also knows about grapheme clusters though I haven’t tested this. Someone had a lot of fun. 
The old latin-1 interface is still there but will be deprecated in the future.

Ah, so there’s an outdated piece of that tutorial
In Elixir, the word string means a UTF-8 binary and there is a
Stringmodule that works on such data. Elixir also expects your source files to be UTF-8 encoded. On the other hand, string in Erlang refers to char lists and there is a:stringmodule, that’s not UTF-8 aware and works mostly with char lists.
We should remove “that’s not UTF-8 aware”?
