In fish shell, with bob-the-fish theme[1] and powerline fonts, my prompt ends in ``. Gives a nice appearance, and definitely isn't a valid redirect.

Of course anyone who does manage to paste and execute code as root (or with sudo in the line) in a terminal without sanitizing it is careless, as long as their terminal doesn't have the stupid right-click-paste behavior. If it does, I agree with the author that it's just a bad terminal.

I wonder if anybody has modified their browser fonts with the powerline characters and can actually see the character you've written here. If those people are anywhere it'd be here. :)

Weirdly, my Firefox displays it in the page as the Unicode box (E0B0), but if I right click and "Inspect Element", it shows the arrow character as it should be, as part of the span tag's content text.
