It will be incorrect if there is double-width characters.

it("double width characters", function() {
  var t = newTermState();
  t.write("ab");
  t.mvCursor(-2,0);
  t.write("\u4e00"); // '一' (chinese)
  expect(t.toString()).to.be("\u4e00"); // expect error
});

Maybe you can use wcwidth or string-width to determine the length of string.
