Thanks for the suggestion. I have attached a marked-up screen shot of an
xterm (left) and gnome-terminal running `emacsclient -nw` and showing
the same buffer. You can see there is a noticeable clipping of some of
the characters in the xterm.

According to lsof, gnome-terminal is using

 /usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf

so the xterm has been run using

xterm -fa 'DejaVuSansMono' -fs 9

(and all font-related options are commented out in ~/.Xdefaults).

FWIW, this is on a debian testing system with XTERM_LOCALE=en_US.UTF-8.
