Questions / Help

Please has anyone experienced this bellow on their windows (conEmu) setup?

C:\
λ iex
Interactive Elixir (1.6.6) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> "µ"
** (UnicodeConversionError) invalid encoding starting at <<230, 34, 10>>
    (elixir) lib/string.ex:2043: String.to_charlist/1
iex(1)> ^CTerminate batch job (Y/N)?
^C
C:\
λ erl
Eshell V10.0.1  (abort with ^G)
1> "µ".
"µ"

I am able to paste "µ" directly into iex console started with --werl without errors as well.

Seems it’s not possible:

Note that "µ" in erlang is 'µ' in elixir and "µ" in elixir is <<"µ">> in erlang.

On my Windows 10 PC:

Elixir:

C:\Users\dimi>iex
Interactive Elixir (1.6.6) - press Ctrl+C to exit (type h() ENTER for help) iex(1)> "µ"
<<0>>

Erlang:

C:\Users\dimi>erl
Eshell V10.0.1  (abort with ^G)
1> "µ".
[0]

That is after you have applied chcp utf-8 or similar code-page.

Without applying a code page, erl gives the expected output: µ
