Issue #9930 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Open to Closed

As of Ruby 3.0, ARGV values are in UTF-8 encoding by default on Windows.

----------------------------------------
Bug #9930: unicode filenames somehow don't work
https://bugs.ruby-lang.org/issues/9930#change-90619

* Author: rogerdpack (Roger Pack)
* Status: Closed
* Priority: Normal
* Assignee: cruby-windows
* ruby -v: ruby 1.9.3p194 (2012-04-20) [i386-mingw32]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
Something seems amiss here--I can't seem to pass in a unicode filename and have it used for reading/opening a file:

~~~
C:\>type read.rb
p ARGV
p Dir['*']
p File.binread(ARGV[0]).size

c:\>ruby read.rb "( бы  бы).mp4"
["( ?\xB0 ?? ?\xB0).mp4"]
["( ?\xB0 ?? ?\xB0).mp4"]
read.rb:3:in `binread': Invalid argument - ( ?бы (Errno::EINVAL)
        from read.rb:3:in `<main>'
~~~

(jruby too, fwiw...)
