Hmm, yeah, that would help.

I know; I'm not entirely happy with it.  If you know a (hopefully 
trivial) filter that transforms any multi-byte sequences in exactly the 
number of bytes that will be visible (and hopefully those bytes should 
be similar to the original UTF-8 content), that would greatly help.

Something that can be used as

... | toplaintext | ...

As in:


tbl man1/memusage.1 \
| eqn -Tutf8 \
| troff -man -t -M ./etc/groff/tmac -m checkstyle -rCHECKSTYLE=3 \
        -ww -Tutf8 -rLL=78n \
| grotty -c \
| col -b -x \
| toplaintext \
| (! grep -n '.\{80\}.' >&2)


For the moment, I'll keep the -Tascii.

I'll investigate if anything like this exists, and otherwise I'll 
consider doing it myself.

Cheers,

Alex
