I have a wingding check mark that is the size and color of the font being used. I would like to increase the size of just the check mark, not the existing text. And also change the color of just the check mark.

As a note, I should mention that I have set up the wingding check mark as an auto correction entry with the letter "z".

I have tried entering the code number for the wingding (254) and also 0254 with the carat ^0254 in the replace field along with the font formatting as size 18 replaced with size 24 and the color I have chosen, but it doesn't work.
I have also tried pasting in the actual check marks from the document into the find and replace fields, but this does not work either.
I have even tried placing the auto correct letter "z" into the fields, but it does not work.

What is the solution?
