Why are there many more glyphs available in Illustrator CS4 than Indesign CS4?

I am in the process of converting a document from Illustrator to InDesign.

Many of the glyphs and ligatures in Illustrator aren't available in Indesign for the same font, Bickham Script Pro.

I checked that all of the opentype settings between the two programs are the same.

I'm currently using suitcase, but I've tried installing font explorer and I get the same problem.

I'm out of ideas... any suggestions?
