I didn't think it would, but wanted to cover all obvious possibilities
before saying anything.

How's \x80 better than an actual euro sign? (As ascii() shows, it's
coming through as \u20ac, which is correct.)

There are two parts to the problem. Idle is interpreting my pasted
text as CP-1252, but then the exec under the covers is defaulting to
something else (Latin-1?). If exec were told to use 1252, then I think
this would probably work (maybe?) - it'd be limited to a subset of
Unicode characters, but it'd function. In theory, the encoding used
between Idle's front-end and the back-end executor should be an
implementation detail, nothing more - as long as they agree, all's
well.

I like interactive mode, it's a great way to test stuff quickly. And
obviously, I do most of my work in 3.4, not 2.7, so this problem
doesn't hit me. But when I need to test Py2 for something, I'd rather
work interactively and iteratively than with the editor mode.
