[R] the invisible question

[Abby Spurdle]

I have no idea what everyone's talking about.
What invisible character????

The black triangle triangle with a question mark renders fine in (my) gmail.
And it's a unicode character used when there was a problem reading
(presumably text) data.

If I copy and paste it into R, it's replaced by a regular question mark.
