Issue #15044 has been updated by naruse (Yui NARUSE).
The assigned value to `ENV` are stored in the process's environment variable.
The encoding of `ENV[key]` is set as locale.
You can get the locale encoding by `Encoding.find("locale")` which is decided based on `Encoding.locale_charmap` which is affected by `ENV["LANG"]` and `ENV["LC_ALL"]`.
Note that `ENV["PATH"]` is returned as filesystem encoding but it is the same as locale encoding on Unix.

$ 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
