One more option:

Maybe just give the cell a custom format.

Format the cells by:
selecting them
format|cells|number tab|custom category
In the "type:" box, put this:

alt-0252;alt-0252;alt-0252;alt-0252

But hit and hold the alt key while you're typing the 0252 from the numeric
keypad.

It should look something like this when you're done.
ü;ü;ü;ü
(umlaut over the lower case u separated by semicolons)

And format that range of cells as Wingdings.

Now, no matter what you type (spacebar, x, anyoldtextatall), you'll see a check
mark.

Hit the delete key on the keyboard to clear the cell.

If you have to use that "checkmark" in later formulas:

=if(a1="","no checkmark","Yes checkmark")

You can just see if the cell is empty.

I want a cell to be formatted as a checkbox. I don't want to use form or
