Message 285539 - Python tracker
V3 of my patch skips the Readline tests in cases involving non-ASCII bytes when the locale seen by Readline would be ASCII. Readline may translate the non-ASCII bytes to escape sequences, and treat them as special Meta (Alt) key combinations. This behaviour depends on Readline configuration (“set convert-meta off” in /etc/inputrc in my case). It also includes a potential workaround for Android, depending on the resolution of Issue 28997.
