On the topic of Japanese Windows users, what type of Ruby builds are they using, mswin or MinGW?

Feature #13488: Set Encoding.default_external to UTF-8 on Windows
https://bugs.ruby-lang.org/issues/13488#change-64485

Currently Encoding.default_external is set to the local ANSI encoding of the Windows installation unless changed per option `-E`. This is cp850 for Western Europe. It should be changed to UTF-8.

The current setting is a major interoperability issue and it is neither useful nor expected, because nobody seriously uses the ancient locale dependent cpXYZ encodings for file content.

If a native encoding shall be used, it should be UTF-16 on Windows. However UTF-16 would make interoperability and compatibility even more difficult. So the only reliable choice for default_external is UTF-8, IMHO.

This is already patched per [1] in the upcoming RubyInstaller-2.4 for Windows release. It additionally requires a few changes to MRIs encoding tests.
