Subject Re: Differences in Chineese output between fop 0.20.5 and fop trunk
Date Fri, 13 Apr 2007 10:39:49 GMT
The most probably reason is that the whole line-breaking is different
from 0.20.5 (the code has been rewritten) and FOP still doesn't
implement all of UAX#14. I can't even tell if 0.20.5 did it right.
Anyway, we mostly lack the knowledge of non-western scripts and have an
incomplete implementation, so effects like this are to be expected.

As a work-around you can try inserting zero-width spaces to give FOP the
chance to add more spacing/break possibilities. From the Unicode docs:
ZWSP: "this character is intended for line break control: it has no
width, but its presence between two characters does not prevent
increased letter spacing in justification."
