Subject: Wide character in stdin causes immediate death with IO::Async::Process
Date: Tue, 31 May 2016 17:09:23 -0700
To: bug-IO-Async@rt.cpan.org
From: Ryan Voots <simcop2387@simcop2387.info>
Simplest test case is attached (not sure yet if RT will attach it, link at end just in case)

Any kind of wide character will cause IO::Async::Process to kill everything when it has IO::Async::Stream send it to IO::Handle and it tries to use syswrite.

Stack trace from IO::Handle (i added a cluck just before it dies to get a full trace).

Where am i? at /home/ryan/perl5/perlbrew/perls/perl-5.22.0/lib/5.22.0/x86_64-linux/IO/Handle.pm line 480.
