Get Custom Number Format

Hi all,

Using Excel 2010.

I would like to generate a report on certain columns for all worksheets in a workbook to review the custom number format for the given cells

I entered a customer number format for a cell as a test : [>=0.986]0.00%♦;

I then tested in the Immediate Window:

And received this output
Is it possible to get the exact output?
That is I should receive a "♦", not a "?"

Thanks
w
