' ``` Part of the underlying issue seems to be that `__FILE__` and `__dir__` are not UTF-8 encoded for the main script, unlike required files. I'm not sure if changing that alone will fix the issue, though. When I run the following script (`f3.rb`): ``` p ['__FILE__', __FILE__, __FILE__.encoding] p ['__dir__', __dir__, __dir__.encoding] p ['Gem.dir', Gem.dir, Gem.dir.encoding] puts 'Gem.path' Gem.path.each do |s| p [s, s.encoding] end puts '$:' $:.each do |s| p [s, s.encoding] end ``` I get the following when using Ruby installed in a non-ASCII path: ``` d:\��>d:\zz-k��nnen2\Ruby31-x64\bin\ruby D:\��\f3.rb ["__FILE__", "D:/\xC5\xE2\xE3\xE5\xED\xE8\xE9/f3.rb", #] ["__dir__", "D:/\xC5\xE2\xE3\xE5\xED\xE8\xE9", #] ["Gem.dir", "d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/gems/3.1.0", #] Gem.path ["C:/Users/jeremye/.gem/ruby/3.1.0", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/gems/3.1.0", #] $: ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/site_ruby/3.1.0", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/site_ruby/3.1.0/x64-ucrt", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/site_ruby", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/vendor_ruby/3.1.0", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/vendor_ruby/3.1.0/x64-ucrt", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/vendor_ruby", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/3.1.0", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/3.1.0/x64-mingw-ucrt", #] ``` and when installed into an ASCII path: ``` d:\��>C:\Ruby30-x64\bin\ruby d:\��\f3.rb ["__FILE__", "d:/\xC5\xE2\xE3\xE5\xED\xE8\xE9/f3.rb", #] ["__dir__", "d:/\xC5\xE2\xE3\xE5\xED\xE8\xE9", #] ["Gem.dir", "C:/Ruby30-x64/lib/ruby/gems/3.0.0", #] Gem.path ["C:/Users/jeremye/.gem/ruby/3.0.0", #] ["C:/Ruby30-x64/lib/ruby/gems/3.0.0", #] $: ["C:/Ruby30-x64/lib/ruby/site_ruby/3.0.0", #] ["C:/Ruby30-x64/lib/ruby/site_ruby/3.0.0/x64-msvcrt", #] ["C:/Ruby30-x64/lib/ruby/site_ruby", #] ["C:/Ruby30-x64/lib/ruby/vendor_ruby/3.0.0", #] ["C:/Ruby30-x64/lib/ruby/vendor_ruby/3.0.0/x64-msvcrt", #] ["C:/Ruby30-x64/lib/ruby/vendor_ruby", #] ["C:/Ruby30-x64/lib/ruby/3.0.0", #] ["C:/Ruby30-x64/lib/ruby/3.0.0/x64-mingw32", #] ``` It looks like the difference in the non-ASCII path case is that `ASCII-8BIT` encoding is used even if the path itself is valid UTF-8. This is true even if you force a UTF-8 code page (though that does fix `__FILE__` and `__dir__`): ``` d:\��>chcp 65001 Active code page: 65001 d:\��>d:\zz-k��nnen2\Ruby31-x64\bin\ruby D:\��\f3.rb ["__FILE__", "D:/��/f3.rb", #] ["__dir__", "D:/��", #] ["Gem.dir", "d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/gems/3.1.0", #] Gem.path ["C:/Users/jeremye/.gem/ruby/3.1.0", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/gems/3.1.0", #] $: ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/site_ruby/3.1.0", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/site_ruby/3.1.0/x64-ucrt", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/site_ruby", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/vendor_ruby/3.1.0", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/vendor_ruby/3.1.0/x64-ucrt", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/vendor_ruby", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/3.1.0", #] ["d:/zz-k\xC3\xB6nnen2/Ruby31-x64/lib/ruby/3.1.0/x64-mingw-ucrt", #] ``` Since there does appear to be an issue, I'll reopen this. Hopefully someone with more knowledge in this area can suggest a possible fix. ---------------------------------------- Bug #15993: 'require' doesn't work if there are Cyrillic chars in the path to Ruby dir https://bugs.ruby-lang.org/issues/15993#change-92849 * Author: inversion (Yura Babak) * Status: Open * Priority: Normal * ruby -v: ruby 2.6.3p62 (2019-04-16 revision 67580) [x64-mingw32] * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- I��m trying to build a cross-platform portable application with Ruby onboard and there is a problem on Windows.
