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.
