How to enter Unicode Character in FrameMaker 10?

[Karen Robbins]

Hello Framers,

I have been struggling with this in FM9. My document has a 
Symbol-font arrow that goes wonky when I convert to PDF. I have tried 
several tools and suggestions, including the FM hex input palette, to 
enter the proper code, but none work--I just get a question mark in 
place of the arrow. I am not skilled enough in Windows (7) to modify 
a registry (Mac person here). Any help for the Windows-impaired?

Thanks,
Karen Robbins
