What steps will reproduce the problem?
(1) Visit a page whose URL contains characters to be %-encoded (e.g. https://ja.wikipedia.org/wiki/%E3%83%A1%E3%82%A4%E3%83%B3%E3%83%9A%E3%83%BC%E3%82%B8)
(2) Copy the URL from the address bar to the clipboard
(3) Paste it to another application (for example, Twitter app)
(4) Confirm some apps (e.g. Twitter) do not recognize a part of the URL.

What is the expected result?

Copied URLs should be %-encoded.

What happens instead?

Copied URLs are not %-encoded. For example, it contains Japanese characters as-is.

It is working as expected in Chrome desktop (confirmed on OSX). Not sure on iOS.
