In both directions, literal dollarsigns can be transmitted by prefixing 
them by backslashes. It is something that is in both the Pd file format 
grammar, and the Tcl file format grammar. It's just not used by IEMGUI.

Because of this, I replace # by a sharpsign prior to using it in a "label" 
message. It works, but it's visibly not the same character, which has a 
different shear to it, and has a wholly different size... looks like 
superscript or subscript.
