    Microsoft Office (Win and Mac) applications ensure that the line breaking is correct for East Asian Text. For example, in Microsoft Word, under Options | Asian Typography | First and Last Characters, you will find the following options for Japanese:


    Cannot Start Line with: !%),.:;?]}¢°’”‰′″℃、。々〉》」』】〕゛゜ゝゞ・ヽヾ!%),.:;?]}。」、・゙゚¢

    Cannot End Line with: $([\{£¥‘“〈《「『【〔$([{「£¥


    There are slight variations for Traditional Chinese, Simplified Chinese, Japanese, and Korean --- which is respected by Word as well.

    We've found an amazing amount of variation in where breaks occur on

    text live on the web... breaks show up everywhere and anywhere, to the

    point where our Japanese morphological analyzer has to ignore

    whitespace (horizontal and vertical) in many situations.(*)


    There is a JIS standard for line breaking, though I don't have a copy

    of it here at home right now. I can look up the "official" rules

    tomorrow if people are interested.




    (*) The worst case we've seen was the use of katanana and hiragana in

        "ASCII" art, Picasso's Guarnica to be exact. Gave our analyzer a

        real fit for a while.
