All I know is that the terminal emulators built into editors and IDEs
like RubyMine often don't support the full range of interactions
possible in a proper terminal emulator, like Terminal or iTerm2. It's
possible JetBrains just didn't implement output of the backspace
character (ASCII 8); I believe it's very seldom used in actually
programs.

Long story short: Use a real terminal, like Terminal or iTerm2.
