Thunderace,
in cell A33 enter the formula =CHAR(ROW()) and copy down to row 255
With the range still highlighted, change the font to Wingdings and you will
see the full Wingdings character set. Character 252 is a tick sign. You
can enter the tick in a cell either by the formula =CHAR(252) with the cell
font set to Wingdings or by holding the the Alt key while you enter 0252
from the number pad keys.
Also have a look to see the full charater set of the other fonts that you
have out of interest.
