Some Unicode chars cannot be displayed properly

[Hongzheng Wang]

Hi all,

It seems that some Unicode characters (rarely used although) cannot be
displayed properly.  That is, when emacs opens a file containing such
characters or user inputs them directly, these characters are not shown
at all.  For example, input the Unicode char 0x3333 (by ucs input
method) between two consecutive ASCII chars, then it is not displayed as
if it does not exist and these two ASCII chars are still adjacent.
However, normal movement commands, say C-f, operates properly on it.
Openning the file saved by emacs through other editor, say gedit, is
also OK.

`what-cursor-position' can show its associated infomation (but display
this character as blank), while `describe-char' reports ``Format
specifier doesn't match argument type''.

Furthermore, emacs -nw (in gnome-terminal for example) does not have
this problem.  So, it may be a GUI related display bug.

Thanks.
