Control-c does not exit, but control-z will. I've tested this in 2.2.0, 2.2.2, and trunk. Please see https://gist.github.com/cantino/48f977bee6a39e33f80f for reproduction. There is an example file with various Unicode Emoji characters in it (borrowed from http://apps.timwhitlock.info/emoji/tables/unicode). I'd like to help fix this if anyone can point me in the right direction. I fiddled with the file until I found a state where it works if one character is removed from the front of the file, so hopefully that's useful information. -- https://bugs.ruby-lang.org/
