Re: emacs could not show this symbol.

Thanks peter_dyballa for your very patient answer!
Pardon for my terrible English, I tried my best to make my expression
clear.

Now I have resolved the problem though don't know why :)
I use this configuration in .Xdefaults:
--------------------------x----------------------------x--------------------------------
  Emacs.Fontset-0: \
  -misc-dejavu Sans Mono-medium-r-*-*-12-*-*-*-m-*-fontset-dejavu,\
  chinese-gb2312:-microsoft-Microsoft 
YaHei-medium-r-*-*-*-*-*-*-p-*-iso10646-1,\
  chinese-gbk:-microsoft-Microsoft YaHei-medium-r-*-*-*-*-*-*-p-*-iso10646-1,\
  gb18030:-microsoft-Microsoft YaHei-medium-r-*-*-*-*-*-*-*-*-iso10646-1,\
  thai-tis620:-misc-fixed-medium-r-*-*-*-*-*-*-*-*-iso10646-1,\
  mule-unicode-0100-24ff:-monotype-courier-medium-r-*-*-*-*-*-*-m-*-iso10646-1

  Emacs.Font: fontset-dejavu
--------------------------x----------------------------x--------------------------------

And this in .emacs:
--------------------------x----------------------------x--------------------------------
(create-fontset-from-fontset-spec
 (concat
  "-misc-dejavu Sans Mono-medium-r-*-*-12-*-*-*-m-*-fontset-dejavu,"
  "chinese-gb2312:-microsoft-Microsoft 
YaHei-medium-r-*-*-*-*-*-*-p-*-iso10646-1,"
  "chinese-gbk:-microsoft-Microsoft YaHei-medium-r-*-*-*-*-*-*-p-*-iso10646-1,"
  "gb18030:-microsoft-Microsoft YaHei-medium-r-*-*-*-*-*-*-*-*-iso10646-1,"
  "thai-tis620:-misc-fixed-medium-r-*-*-*-*-*-*-*-*-iso10646-1,"
  
"mule-unicode-0100-24ff:-monotype-courier-medium-r-*-*-*-*-*-*-m-*-iso10646-1"))
  (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)
                    '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"))

  (set-fontset-font "fontset-default"
                    'thai "-misc-fixed-medium-r-*-*-*-*-*-*-*-*-iso10646-1")
(set-default-font "fontset-dejavu")
(add-to-list 'default-frame-alist '(font . "fontset-dejavu"))
--------------------------x----------------------------x--------------------------------
Now emacs could use fixed and dejavu  for those symbols.

Another question, maybe emacs.font-backend is enabled by default?
I comment it and find that xft is going on well. Don't know what's the
most correct way to configure fontset for xft emacs, although I tell
emacs to use fontset-dejavu, I find that emacs doesn't use this fontset
actually. And many times emacs could not align a line correctly, for
example, in my bookmark buffer, it shows:
  .emacs                        ~/.emacs
  equation.tex                  ~/doc/work/pk/equation.tex
  tip-font                      /usr/home/anhnmncb/doc/tips/tip-font
  tip-words-pro                 ~/doc/tips/tip-words-pro
So weird for me! Anyway, now emacs can display most of the symbols.
