[R] [R-SIG-Mac] character set problem

[Kevin Ushey]

If I understand correctly, the problem is that the character your keyboard
is inserting is not a regular caret (^, \u0053); rather, it's a 'modifier
character circumflex accent' (ˆ, \u02c6).

How are you inserting the carat on your laptop? For what it's worth, I get
a 'regular' caret with Shift + 6, and that particular accent character with
Alt + I.
