I had thought printing an arrow would be simple :-(
I tried the following
?"↓"
?asc("↓")
?chr(63)

The first printed a down arrow
The second gave an output of 63
And last gave an output of ?

The first option was obtained by pressing Alt + 2 5 of numeric key pad
(https://www.alt-codes.net/arrow_alt_codes.php has complete list of alt
codes)

I have tried ?"a↓b" and it gave the desired result.
Have not tried in report or form
