Some fonts (CJK) don't have a space glyph defined, and afmtodit can't add a
spacewidth directive to the troff font, and you have no way of knowing you
needed to add a -w flag until after the font is installed and troff starts
complaining, even though the output is fine.

Not having the hyphen glyph is weird, each time you run with the man macro
(and possibly others), you get this message:-

troff:/home/derij/groff-git/groff/build/../tmac/an.tmac:1512: warning:
character '-' not defined

This is because some devices have a hyphen in their name, so code such as
this:-

.  if '\*[.T]'X75-12' \
.    nr S 12
.  if '\*[.T]'X100-12' \
.    nr S 12

Triggers the warning! Perhaps a judicious use of \f(TR and \fP would fix?

I found these minor issues when developing the UTF-16 bookmark support for
gropdf. See attached Japanese man page.
