Word Macro to display a table showing each character in a font?

I’m looking for a Word macro that can generate a table, with cells containing each character in the font, along with the same character in Arial and also the character code.

The reason for this is that I have a number of wingding-like fonts, and often, I don’t know the keystroke or character code for a given symbol. A chart like this would be much more useful that something like charmap.exe

Does anything like this exist? Or perhaps a standalone program to do the same thing? I’ve google high and low, and haven’t been able to find anything like it.
