If you're making the PL/TFM using \installrawfont, you just need to make an
MTX file saying

\setrawglyph{compwordmark}{<font>}{<designsize>}{<slot>}{0}{\int{xheight}}{0}{0}

this will cause a CHARACTER entry for compwordmark with the desired glyph
dimensions to be written to the PL, and that will satisfy TeX. When a DVI
driver encounters this character (\char 23) in a DVI file, it will treat it
as any other character and write postscript instructions for drawing the
character. The printer will look up entry 23 in the font's Encoding array
(which you have set by reencoding the font) and sees that character 23 is
the glyph .notdef', which it then draws. Every PS font must contain a
glyph named .notdef.

BTW, the designsize and slot entries in the above \setrawglyph are not used
in \installrawfont (\etxtopl); they're only needed when writing a VPL.
