Then login to the new user and run in cmd: ``` C:\Users\kanisä>ruby -e "p Dir.home" "C:/Users/kanis\xE4" C:\Users\kanisä>ruby -e "p Dir.home.encoding" #<Encoding:UTF-8> C:\Users\kanisä>ruby -e "p Dir.home.encode('utf-8', 'iso-8859-15')" "C:/Users/kanisä" C:\Users\kanisä>echo %USERPROFILE% C:\Users\kanisä ``` `Dir.home` should encode the path in UTF-8. Instead the string is labeled as UTF-8 but bytes are encoded in `iso-8859-15`. All versions between ruby-3.0 and current master branch are affected. -- https://bugs.ruby-lang.org/
