repl: surrogate pair upsets repl / terminal

# screen freezes

The REPL still accepts input but no longer echoes it. Typing in process.exit() cleanly shuts down the process but the terminal isn't reset, leaving it in an unusable state until you run reset(1).

Unable to replicate the behavior in io.js 1.0.4 on macosx 10.10.

Sorry, I should have mentioned that this is with v1.x HEAD and that I can reproduce it with the stock FC21 terminal emulator and with the OS X 10.8 terminal emulator when ssh'ing into an FC21 box but not when run locally - and only when TERM=screen, TERM=xterm works.

[jasnell]

Ah... Just for completeness... did you double check the locale on the FC21 box?

[bnoordhuis]

It's en_US.UTF-8. Starting screen with e.g. LC_ALL=C doesn't make a difference. I'm not sure if screen is locale-aware, though.

Seems to work fine on mine...?

(I can't seem to copy that character to my clipboard though..)

Oh, missed that.
