paginated reports-export to pdf

[ldwf]

Hello, I have a paginated report for which I have the up and down small black triangle symbols in a column.  They show up fine when I run the report as well as when I export to Excel, but when I export to PDF,  they show up as empty squares.  I define the symbols using the ChrW(9650) and ChrW(9660).  I set the font family to " ".  Any suggestions as to how I can get this to export to PDF correct?  Thanks for any assistance.
