combining marks for currency characters? general combining character?

Hi Kim,

While it can be argued that the "NON-DESTRUCTIVE BACKSPACE" capability of a
typewriter, allowing arbitrary overstruck characters, belongs to plain
text, it is more akin to creating subscripts and superscripts by rotating
the platen knob up or down by half-interval, which Unicode considers to be
within the domain of markup rather than plain text.
