set-fontset-font and preferred charset?

[Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp>]

Hello,

Is there any way to specify different fonts for the same character
with different preferred charsets?

For example, I want to display cyrillic/greek characters using
jisx0208.1983 fonts (wide characters) in Japanese charset texts, and
iso8859-* fonts (narrow characters) in other context (such as email
from other countries).

In other word, how can I specify different fonts for the following two
characters?

        character: д (1076, #o2064, #x434)
preferred charset: cyrillic-iso8859-5

       code point: 0x54
           syntax: w 	which means: word
         category:

      buffer code: #xD0 #xB4
        file code: ESC #x2C #x4C #x54 (encoded by coding system iso-2022-7bit)
          display: by this font (glyph code)
    x:-misc-fixed-medium-r-normal--14-130-75-75-c-70-iso8859-5 (#xD4)

(it seems that the characters in this mail were unified into
iso-2022-jp by the mailer... I picked up the first one from HELLO
file.)

The following settings supercede each other and don't work well.

(set-fontset-font "fontset-startup"
 		  'japanese-jisx0208
 		  '("misc-fixed" . "jisx0208.1983"))

(set-fontset-font "fontset-startup"
 		  'cyrillic-iso8859-5
 		  '("misc-fixed" . "iso8859-5"))
