My Emacs 23 displays U+202F as a rectangle in many fonts, e.g.
-Adobe-Helvetica-Medium-R-Normal--17-120-100-100-P-88-ISO10646-1
(helvR12.pcf.gz from xfonts-100dpi 1:1.0.3 on Debian 8.6).
Playing around with xfontsel -sampleUCS and xfd -fn, I see that
-Misc-Fixed-Bold-R-Normal--18-120-100-100-C-90-ISO10646-1
(9x18B.pcf.gz from xfonts-base 1:1.0.3 on Debian 8.6) likewise
displays a rectangle, but the non-bold variant (9x18.pcf.gz)
displays a space for U+202F.

Maybe things look better with FreeType but not everything uses that.
