bug#1096: The Emacs 23 cann't display the cjk extb characters again.

Dear all,

Now, I updated the Emacs 23 to 23.0.60.1 (i386-mingw-nt5.1.2600) of 2008-10-03 on LENNART-69DE564, then I find that I cann't see the correct cjk extb characters displayed by this version.  For example, the Chinese character uni20021, a character of cjk extb, which can be displayed correctly by using the previous versions by LENNART, cann't be displayed correctly now.  In addition, I can display that character on my box with emeditor, denoting that I've the corresponding fonts installed correctly.  Finally, I've use the following settings in my _emacas file which is suggested by Kenichi Handa:

--------------
(if (display-graphic-p)
(set-fontset-font
 (frame-parameter nil 'font)
 '(#x20000 . #x2fa1d)
 '("*-Sun-ExtB" . "unicode-sip")))
--------------

In addition to that change, which should help with displaying those 
characters by default, it turns out there is a bug in the Windows 
function that we use to encode characters into glyph points when passed 
a surrogate pair. I've worked around it by using an oversized glyph buffer.

Hi Handa-san,

Could you take a look at this bug report?  Thanks.

I've just installed a fix.  At least with Xft font backend,
Emacs should be able to find a proper font for the Unicode
SIP area (#x20000..#x2FFFF) now.

At least part of the problem here is that the font name contains a -, which is
not compatible with the use of xlfd as the internal representation of fonts.

That is why I suggested as above; i.e. prepend "*-" to the
family name so that the parser knows that foundry is nil and
the remaining part is a family name.

By the way, the above notation is kept for backward
compatibility (and also for handy way).   The cleaner code
is:

(set-fontset-font
 (frame-parameter nil 'font)
 '(#x20000 . #x2fa1d)
 (font-spec :family "*-Sun-ExtB" :registry "unicode-sip"))

because we are now using font-{spec|entity|object} as the
internal representation of fonts.
