Heirloom troff has also implemented the .char request (recognized when using -x2 or higher), and its -a output works as expected.

$ printf ".char a z\nplan\n" | heirloom-troff -a -x2

$ printf ".char a z\nplan\n" | groff -a

When the .char request is used in groff 1.22.4, correct output is produced for PostScript or TTY:

printf ".char a z\nplan\n" | nroff | grep pl.n
printf ".char a z\nplan\n" | groff | grep pl.n

But incorrect output is produced for ASCII approximation via -a:

printf ".char a z\nplan\n" | groff -a | grep pl.n
