How do I get Prince to display a checkmark?

Currently using &#0252 with Winding font and it works in HTML.

I know Prince has characters mapped in the private use area. Is there a map of what is mapped to what?[/code]

You can access the 256 glyphs in Wingdings and other non-UNICODE fonts by using the characters in the private use area starting from &#xF000 or in decimal &#61440. The check mark is thus &#xF0FC or &#x61692, which is 61440 + 252.
