Rather than going into hexl-mode, try pressing C-u C-x = on both 
characters and compare the results.
I suspect that one of these is coming from the mule-unicode-0200-3fff 
character set, and the other from some other character set so uses a 
different font.

If you have a better matched iso10646-1 font on your system, you can 
define a fontset that explicitly includes that font for the 
mule-unicode-* charsets. See the section "Defining fontsets" in the 
Emacs manual for more details.
