why? indesign CS6 does not support " Adobe SING Glyphlet Manager"?

I creat the  Symbol with Ai CS3. I want to make the symbol  change to "font".

I only can find  Adobe SING Glyphlet Manager CS3,  I do it Step by step，I can find the font "ExtraGlyphlets",can get the Symbol that I need,

But,I need use the Sybol in the ID Cs6,I Can't find the "ExtraGlyphlets" font in CS6

And,How  could I delete the green Area，for I donot need it?
