Good call!  Each of the fonts I tried which behave the same all fall back
to FreeMono for this character.  If I uninstall FreeMono, then rxvt-unicode
reports that it is using the "built-in support font".  The built-in font
works as expected, just like the UCS font
'-Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO10646-1'.

To see if other programs might have an issue with FreeMono, I used pango
to render a PNG with the character, and it renders the keycap character
0x20E3 only one space back.  I think it might be the extra kerning with
FreeMono which is part of the problem.

Thanks.
