Omega symbol becomes W in pdf

[Nancy Allison]

  OK, I set Adobe PDF as my default. Same results.

However, someone pointed me to a document that worked correctly. The 
ONLY difference I can see between that doc and mine is that the writer 
did NOT create a Frame character tag called Symbol that applied the 
Symbol font (Symbol, not Symbol Std).

Instead, he evidently went to the Format/Fonts menu and applied Symbol 
(not Symbol Std) directly from there.

The characters I created that way survived the translation to PDF. (So 
did the characters I cut and pasted from the correct doc into mine. So 
evidently the Distiller font settings are not the issue.)

Any thoughts as to why this made a difference?

Thanks one and all -- what a nasty problem.
