Bug #19243: Windows: Dir.home returns string in wrong encoding

https://bugs.ruby-lang.org/issues/19243#change-102541



* Author: larskanis (Lars Kanis)

* Status: Closed

* Priority: Normal

* ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x64-mingw-ucrt]

* Backport: 2.7: UNKNOWN, 3.0: REQUIRED, 3.1: DONE

----------------------------------------

Create a new local user on Windows called "kanis=E4".

Then login to the new user and run in cmd:



```

C:\Users\kanis=E4>ruby -e "p Dir.home"

"C:/Users/kanis\xE4"



C:\Users\kanis=E4>ruby -e "p Dir.home.encoding"

#<Encoding:UTF-8>



C:\Users\kanis=E4>ruby -e "p Dir.home.encode('utf-8', 'iso-8859-15')"

"C:/Users/kanis=E4"



C:\Users\kanis=E4>echo %USERPROFILE%

C:\Users\kanis=E4

```



`Dir.home` should encode the path in UTF-8. Instead the string is labeled a=
s UTF-8 but bytes are encoded in `iso-8859-15`.



All versions between ruby-3.0 and current master branch are affected.
