* [ruby/reline] We still need support new and legacy behavior.
Revert "Support for change in Windows-specific behavior at eol"

https://github.com/ruby/reline/commit/646587fc2c

https://github.com/ruby/reline/commit/3535676689

* [ruby/reline] Use UTF-8 only for width calc, rest uses original encoding

I confirmed that libvterm supports only which are UTF-8, US ASCII, UK, and
DEC graphics by reading source code, so can't test this patch by
yamatanoorogi gem through vterm gem for now.

This fixes ruby/irb#190.
