File.join generates corrupted Windows-31J String on Windows

[headius]

From http://jira.codehaus.org/browse/JRUBY-7131

The original bug report did not have a good reproduction, so we'll need a Windows machine and we'll need to figure out how to type Unicode into a terminal to reproduce this.

I'm going to pessimistically guess it's still broken, but for now this bug is a placeholder until we can confirm that.

cc @nahi, who filed the original report.

IRB in Java window displays correct characters, but original windows console is ascii only
???/??? instead of 日本語/日本語

[headius]

My environment seems screwy and won't display multibyte chars in Command Prompt, but it does appear to join the filenames correctly. Can someone reproduce the File.join problem and show me:

• a git repo with a reproduction file
• a session log showing the failure OR a short video showing the failure

Multiple years with no repro. Closing. fwiw continued work on appveyor test runs are straightening out some of these issues over time but without a repro I don't know if this is one or not.

@enbo I think it was already fixed in 9000 by #3871 - it shoud be closed, thanks
