Rudimentary implementation of the roff(7) .char (output glyph

definition) request, used for example by groff_hdtbl(7).

This simplistic implementation may interact incorrectly
with the .tr (input character translation) request.
But come on, you are not only using .char *and* .tr, but you do so
with respect to the same character in the same manual page?
