Not necessarily.

Technically it's possible but there's no standard way.
First of all, I don't know if there's an agreement about
what registry-encoding to use for an X font for Unicode SIP
area.  So here I assume that you somehow manage to get an X
font whose registry-encoding part name is "iso10646-2".  I
can't tell how to make your TTF recognized by X server as
such a font.

Anyway, once you confirm that your font is working on X by,
for instance, xfd as below:

% xfd -fn .....-iso10646-2

what you have to do is this:

(push '("iso10646-2$" . unicode-sip) font-encoding-alist)
(set-fontset-font
 "fontset-default" 'han '(nil . "iso10646-2") 'append)
