Description Frank Closset 2001-11-03 05:22:02 UTC 
When formatting a chinese document the wrap property does not work well. 
Sometimes an overflow takes place, and for now I can't explain why this happens 
at that moment.

I use following font "Arial Unicode MS"

Does anybody have the same problem?

After tracing the source code, I found the wrapping occurs in class
    org.apache.fop.layout.LineArea
Further tracing shows that the method:
    private boolean canBreakMidWord() 
affects the wrapping result. Notice that when variable hyphProps.language 
has value of "zh", "ja", "ko", "vi", the function will return true, where
proper wrapping will be display.
My temp solution is to specify a "language" property in block, e.g.
    <fo:block font-family="SimSun" wrap-option="wrap" language="zh">
    </fo:block>
It turns out that the wrapping is working.

I believe that this shouldn't be counted as a solution. FOP DOES support
wrapping on CJK characters, but somehow there's no notes available on this,
or the configuration on FOP should be refined?
