Are all pictogram fonts broken in Lion?
I think the fonts are fine - I've just checked them in Font Book.

I tried Text Edit, Pixelmator and Pages and they all do as you state. But, if you load Font Book and find the fonts they are visible and populated with "dings". Could it be that the codes are different due to using Unicode?

To get to Wingdings characters in the other apps:


In Keyboard Preferences check "Show Keyboard &amp; Character Viewers in menu bar".
In the menu bar these is now a new icon.
Click on the icon and select "Show Character Viewer".
Characters can then be cut and paste from the Character Viewer.
