        <p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Originally
            in APRSdos the overlay characters were drawn over the symbol
            itself and those symbols were drawn to have a clear spot in
            the center.</span></p>

        <p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Then
            in the Kenwoods, we suggested placing the overlay character
            in the upper left corner so that they could appear over
            any/all symbols.</span></p>

style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">In
            any new system I suggest 2 bits be allocated to indicate
            where the overlay character is drawn.  Upper left, Upper
            right, center, or none.  “None” can be used when a client
            that has defined a separate symbol for a given overlay combo
            because it does not then also need to draw the overlay
            character.  Though if there is room, it would help human
            understanding across platforms if the overlay character was
            also obvious on the new special symbol.</span></p>
