^C is only the default interrupt character. From some basic testing, it
seems you can use tcgetattr/tcsetattr on the master side of the pty.
So the terminal could perhaps disable isig before writing the string
and restore it afterwards. I doubt that an ssh would pass that through,
however.

Would have been better if xterm had done it that way in the first place. 
As it is, stripping a fake end string should do the job.

I've got a widget based on xclip. There isn't always an X connection
back, however. It might be worth remembering for when copying text from
firefox.

The nice thing about getting bracketed paste working is that it
potentially doesn't require users to learn anything new: they already
know how to paste in their terminal. That's also why I think it is worth
trying to include support in a form that doesn't need ohmyzsh plugins or
lines in .zshrc. And putting security aside, there are other benefits
like the single undo event, newlines not being accepted and the option
of manipulating the string such as with shell quoting.
