Some question about fontsets

[wang yin <wy@wangyin.com>]

Hi,

I asked question about fontsets a few days ago. But
I still have problem with the IPA characters [igzɑːmpl].

C-u C-x = gives the information:

  character: ɑ (01210721, 332241, 0x511d1)
    charset: mule-unicode-0100-24ff
	     (Unicode characters of the range U+0100..U+24FF.)
 code point: 35 81
     syntax: word
   category:
buffer code: 0x9C 0xF4 0xA3 0xD1
  file code: 0x9C 0xF4 0xA3 0xD1 (encoded by coding system emacs-mule-unix)
       font: -Adobe-Courier-Medium-R-Normal--14-140-75-75-M-90-ISO10646-1

I've read the Emacs manual about the fontsets, and set my fontset 
in ~/.Xdefaults as follows:

Emacs.Fontset-0: -*-fixed-medium-r-normal-*-24-*-*-*-*-*-fontset-wangyin,\
        chinese-gb2312:-*-simsun-medium-r-normal-*-24-*-gb2312*-*,\
	mule-unicode-0100-24ff:-b&h-*-*-r-*-*-14-*-*-*-*-*-iso10646-*

Emacs.Font: fontset-wangyin

But it still can't be displayed properly.
I use the describe-fontset function but I get the error:
"Current frame is using font, not fontset"

It seems none of my fontset settings can work!
I Shift-mouse1 to change the fontset, but nothing happens.

What's wrong? And how can I display the IPA characters?
