Handling of space between Kanji and non-Kanji characters.


1. Shibuaki or Yonbuaki ($B;MJ,$"$-(B)



         <Japanese Text> English word <Japanese Text>
                        ^            ^
                    This point   This point 

    This space is called "Shibuaki" which has a width of a quarter of a kanji
    font width. It is used only between Kanji and non-Kanji characters.
    (between Kanji and Kanji only stretchable glue is used; between
    ASCII and ASCII ordinary space.)


2. Yakumono($BLsJ*(B)

    Here are the rules how and where to use Shibuaki.

2.1 Yakumono for ASCII characters

   rules:

    0   No shibuaki between previous kanji character and the ASCII
        character, and between next kanji character and the ASCII
        character.

          <Kanji character><ASCII character><Kanji Character>

    1   Shibuaki space only between previous kanji character and the
        ASCII character.

          <Kanji character> <ASCII character><Kanji Character>
                           ^            
                        shibuaki

    2   Shibuaki space only between next kanji character and the ASCII
        character.

          <Kanji character><ASCII character> <Kanji Character>
                                            ^            
                                         shibuaki

    3   Shibuaki spaces between kanji characters and ASCII word.

          <Japanese Text> English word <Japanese Text>
                         ^            ^
                      shibuaki     shibuaki


   Rule 3 is always used by all printable ASCII characters without
   the following yakumono ASCII characters.

        character.

          <ASCII character> <Kanji character><ASCII character>
                           ^            
                        shibuaki
