Ruby Problem with Unicode

Hello,

i wrote this:

class DerGanzeSatz
  attr_reader :arg1

 def initialize(arg1)
   unify(arg1)
 end

 def unify(arg1)
   arg1 = arg1.unicode_normalize!
   splitting(arg1)
 end

 def splitting(arg1)
   split_all = arg1.split(/\W+/)
   washing(split_all)
 end
 def washing(arg1)
   washing = arg1
   washing.uniq!
 end
end

truewords = []
print "> "
write = DerGanzeSatz.new(gets.chomp)

and it always gives out that error:

ruby test.rb
> In diesem Satz kommen Wörter doppelt vor! Den Wörter kommen in Sätzen oft doppelt vor!

Traceback (most recent call last):
6: from /test.rb:26:in `<main>'
5: from /test.rb:26:in `new'
4: from /test.rb:5:in `initialize'
3: from /test.rb:9:in `unify'
2: from /test.rb:9:in `unicode_normalize!'
1: from /lib/ruby/2.5.0/unicode_normalize/normalize.rb:126:in `normalize' 
lib/ruby/2.5.0/unicode_normalize/normalize.rb:126:in `gsub': invalid byte sequence in UTF-8 (ArgumentError)

Does someone have a hint how to deal with that problem WITHOUT stripping letters?

I believe your problem is in this code:

def washing(arg1)
   washing = arg1
   washing.uniq!
 end
# you are calling the method inside of the method without an argument
# I would change the local variable 'washing' to washing_1 or something so you don't get the error.
# make sure that you change the return variable name as well.

Hi thanks for your participation. The code works, as long as you type just english words. If you beginn to type german (which is nescessary for the programm to have use, once it done) you get this message. My System is UTF-8, my editor saves in UTF-8 and well.. just ruby seems not to understand non-english letters.

Even if I try to use .encode(UTF-8) or .force_encoding(UTF-8)... everything runs into this error message.
