Here's what's worked for me on vehicles with escutcheon and pinned handle - YMMV.
Compress one side of the escutcheon and insert a long, thin nail-set (slightly smaller diameter than the pin) between it and the handle. Hold the nail-set with one hand and compress the other side of the escutcheon with your other hand. Push the pin out with the nail-set. Once you get the pin started, grab it with pliers and pull it out. If the pin is stubborn, have a helper tap on the nail-set with a hammer. The nail-set gives you something to hold on to, pound on, and leverage as necessary.
