Bug #11444: STDIN.each_codepoint hangs indefinitely on certain codepoints
https://bugs.ruby-lang.org/issues/11444#change-55185
* Author: Andrew Cantino
* Status: Closed
* Priority: Normal
* Assignee:
* ruby -v: ruby 2.3.0dev (2015-08-13 trunk 51569) [x86_64-linux]
* Backport: 2.0.0: REQUIRED, 2.1: DONE, 2.2: DONE
----------------------------------------
Piping certain Unicode data into Ruby and calling `each_codepoint` on `STDIN` results in a hang. 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.
