Viewing the PostScript produced by tr2post, turns out it uses the font
LucidaSansUnicode25 to render the square, which means you need to have
these fonts installed to $PLAN9/postscript/font and then call "psfonts"
programs to embed the PostScript font.

The "NOTICE" file at $PLAN9/postscript/font says:

So you'll need to find the distribution of Plan9 which has following files
LucidaSans-Demi
LucidaSans-Italic
LucidaSans-Typewriter83
LucidaTypewriter
NOTICE
ams
cm
fontmap
lino
lsunr00.pfa
lsunr01.pfa
lsunr02.pfa
lsunr03.pfa
lsunr04.pfa
lsunr05.pfa
lsunr20.pfa
lsunr21.pfa
lsunr22.pfa
lsunr24.pfa
lsunr25.pfa
lw+

You will need to *append *the fontmap file to $PLAN9/postscript/font/fontmap and copy the files `Lucida*` and `*.pfa`, and optionally `cm` and `ams`.

Then `9 tr2post file.dpost | 9 psfonts > file.ps` would render the symbols properly.

You can also use `dpost` from heirloom-doctools to render the troff output to PostScript, saves the procedure to manually install the fonts.
