What is the best way to display a checkbox in a Crystal Report?

Example: My report has a box for "Male" and "Female", and one should be checked.

My current workaround is to draw a small graphical square, and line it up with a formula which goes like this:

if {table.gender} = "M" then "X" else "  "

This is a poor solution, because changing the font misaligns my "X" and the box around it, and it is absurdly tedious to squint at the screen and get a pixel-perfect alignment for every box (there are dozens).

Does anyone have a better solution? I've thought about using the old-style terminal characters, but I'm not sure if they display properly in Crystal.

Edit: I'm using Crystal XI.
