Learning Erlang after Elixir

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Ah, so there’s an outdated piece of that tutorial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 String module 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 :string module, that’s not UTF-8 aware and works mostly with char lists.

We should remove “that’s not UTF-8 aware”?
