emacs could not show this symbol.

[anhnmncb]

        character: ๑ (3665, #o7121, #xe51)
preferred charset: gb18030 (GB18030)
       code point: 0x8132D639
           syntax: w    which means: word
         category: 6:digit t:Thai
      buffer code: #xE0 #xB9 #x91
        file code: #xE0 #xB9 #x91 (encoded by coding system utf-8-unix)
          display: no font available

How to configure emacs to show this symbol? I'm quite sure I have the
font that contains it, because urxvt and opera (yes, I use opera to test
it ;p) could. urxvt use "wenquanyi zen hei", I don't know how to get the
font info opera uses.

My .emacs font setting:
  (set-default-font "Bitstream Vera Sans Mono-12")
  (set-fontset-font (frame-parameter nil 'font)
                    'latin '("Bitstream Vera Sans Mono" . "unicode-bmp"))
  (set-fontset-font (frame-parameter nil 'font)
                    'han '("Microsoft YaHei" . "unicode-bmp"))
  (set-fontset-font (frame-parameter nil 'font)
                    'cjk-misc '("Microsoft Yahei" . "unicode-bmp"))
  (set-fontset-font (frame-parameter nil 'font)
                    'bopomofo '("Microsoft Yahei" . "unicode-bmp"))
  (set-fontset-font (frame-parameter nil 'font)
                    'gb18030 '("Microsoft Yahei". "unicode-bmp"))
  (set-fontset-font "fontset-default"
                    'gb18030 '("WenQuanYi Zen Hei". "unicode-bmp"))
  (set-fontset-font "fontset-default"
                    'mule-unicode-0100-24ff
                    '("Courier New". "unicode-bmp"))
  (add-to-list 'default-frame-alist '(font . "Bitstream Vera Sans Mono-12"))
