Issue #19243 has been updated by larskanis (Lars Kanis). Patch is here: https://github.com/ruby/ruby/pull/6958 ---------------------------------------- Bug #19243: Windows: Dir.home returns string in wrong encoding https://bugs.ruby-lang.org/issues/19243#change-100709 * Author: larskanis (Lars Kanis) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x64-mingw-ucrt] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- Create a new local user on Windows called "kanisä". 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/
