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

(jruby too, fwiw...)

• Category set to platform/windows
• Assignee set to windows
• Target version set to 2.2.0

ARGV is still in the default external encoding, i.e., console codepage.

We'd like to make them UTF-8, but have no concrete migration plan yet.

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