[PHP] Unicode TTF Font wingding's just don't cut it!

[hugh danaher]

Help 
Does anyone know where I can get a simple symbol font which is .ttf and "unicode" 
compatible.  Seems that my php graphic program is very sensitive to ttf problems.  
It'll take one or two wingdings in imagettftext() before it up and dies.  
Your help will be greatly appreciated.
