$ irb
2.5.1 :001 > 'secret'.encoding
 => #<Encoding:UTF-8>
2.5.1 :002 > ENV['PASS'] = 'secret'; ENV['PASS'].encoding
 => #<Encoding:US-ASCII>
2.5.1 :009 > ENV['PASS'] = 'Ł'
 => "\u0141"
2.5.1 :010 > ENV['PASS'].encoding
 => #<Encoding:ASCII-8BIT>
~~~
I would expect all encodings to be **UTF-8** at all times
