Install Wingdings on Site – How To and Good or Bad Idea?

I am trying to upload a blog post with a table in it. I’m using Windows Live Writer to create the post, copying the table from Excel, where I generate it. The table has some Consumer Reports-style symbols in it (full circles, donut-hole circles, etc.) that are actually characters in Wingdings 2.

When I create the post in Live Writer, it looks great. Then I post it to my site and the symbols turn to random characters (actually the same characters in another font, I assume).

I am new to WordPress and have no idea how to install a new font or tell it how/where to appear. I also don’t know if it’s even a good idea to try to do this with Wingdings 2 or should I figure out a workaround?
