pdf export problem

Hello All-

I have been having problems exporting notebooks to pdf and was hoping  
someone might have some insight.  I submitted a support request to  
Wolfram, but have not heard back.

Quick background:  Mathematica 7.0.0; Macintosh Front End (OS X Leopard 10.5.6).

Quick summary:  I am writing "handouts" for distribution in a math/ 
stats class.  Some characters disappear when converting to pdf.   
Example that has been vexing me lately is the less-than-or-equal-to  
sign (unicode character 2264, I think).  I just get blank spaces in  
its place.

My theories (obviously wrong or I wouldn't be here asking!):  I  
thought it was a problem with font installations, but I have tried  
different fonts without success.  I also have noted that the problem  
occurs when the cells are "text" style, but goes away if I make the  
cell "equation" style.  I can't decide if there is a problem in the  
style definitions, a bug that improperly defines fonts (and/or misses  
embedding) into pdf, or something to do with "high" unicode characters.

Apologies if my perusal of the archives has missed another discussion  
of this issue, but thanks to anyone who can offer any insight or  
help.  I thought such font problems were well in my past, but no such
