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"))) -------------- Please find the snapshot of this issue in the attachments.
