AE doesn't support full Unicode features and can't do the necessary glyph substitutions, ligatures and what have you. you will have to create the text in another program and import it as a graphic.
for giving me your feedback.
but i think there is something which we are unable to find it.
In flash we use TLF text for solving this type of problems, same Flash is a part of ADOBE same After Effect is also a part of ADOBE.
May be something like TLF text is in After Effect.
