I'm seeing a behavior that I believe to be a bug. When I have a phonetic spelling with a tie character—for example, d͡ʒ"—using Indesign's paragraph composer, Indesign renders it as three characters—d + [tie] + ʒ. When I change to the world-ready paragraph composer, however, InDesign joins the tie to the character before it such that it can't be moved. I tried using a non-joiner between them, but InDesign just joins the tie to the non-joiner.
