Hi,

in Emacs 22.2.50, "zero width no-break space" (U+FEFF) is displayed as
a hollow box. [1]

I think for normal buffers it should be displayed like ` ' (NO-BREAK
SPACE, U+00A0) i.e. using the face face `nobreak-space'.  But when
`nobreak-char-display' is nil, it should not be displayed at all or
like a normal SPC.  (Dunno what Unicode says about it.)

In gedit, xedit (with the same font as in Emacs) and Firefox[2], the
char is displayed like a space char (i.e. not "zero width").

Bye, Reiner.
