How can I split a string only at spaces with unicode characters in it?
I am a newbie in Elixir and am trying to split String only at spaces the string contains unicode charcters too
String.split("Freude schöner Götterfunken", ~r/[^[:alnum:]-]/u, trim: true)
like above , this gives me a UnicodeConversionError , is there a way to do that ?
the output I want is
["Freude","schöner","Götterfunken"]
It would be great if someone could suggest something.

Thanks a lot for all your help ,
My requirement was I have to split a string on spaces discarding all the symbols except a few special characters like a ‘-’ , after lot of trial and errors the below regex solves it ,
String.split(sentence, ~r/[^[:alnum:]-]/ui, trim: true)
This is a great forum and hope it will help someone in need 
Thanks again for the help , I come from Java and have started on elixir , you can imagine the pain its a whole new world for me , will post questions if any .

String.split("Freude schöner Götterfunken") would be preferred since it will use the Unicode word break algorithm which is much more flexible than breaking on an ASCII space character.
iex> String.split("Freude schöner Götterfunken")
["Freude", "schöner", "Götterfunken"]
From the docs:
Divides a string into substrings at each Unicode whitespace occurrence with leading and trailing whitespace ignored. Groups of whitespace are treated as a single occurrence. Divisions do not occur on non-breaking whitespace.

This works for me:
iex(1)> String.split("Freude schöner Götterfunken", ~r/[^[:alnum:]-]/u, trim: true)
["Freude", "schöner", "Götterfunken"]
Is your shell not in UTF8 perhaps?
