Hi

I am using FOP 0.93 in a Windows environment. I'm also using an en-
US hyphenation table from OFFO.
What I would like to find out is:
1. Should the ZWS work, and if so, what might cause it not to work?
Last I heard, someone actually did use ZWSP with 0.93 and there was
still a tiny problem there since the renderer inserted a placeholder
glyph # in the result (bug that was recently fixed in FOP Trunk).
That said, the linebreaking should work, IIRC. No immediate idea on
why it isn't working in your case... Is it possible to post a small
fragment of your FO that shows the problem? Say one block with ZWSP
and one block without? That could already help us a lot in figuring
this out.
2. Are there alternatives for creating a line-break after an
underscore? (I tried customizing a hyphenation pattern in
the en_US.xml hyphenation file and pointing the cfg.xml
<hyphenation_base> to point to its directory, but this did not
appear to work for me either - output shows the hyphenation file is
being read, but the new pattern apparently is not
being processed. I tried changing the hyphen character in the en-
US.xml file, and that did not get picked up either.
WRT the patterns: how exactly do you alter them? Do note that in
principle you can only mark the favorability of a hyphenation point,
and that is not an absolute...
Also, I recently noticed that if you would supply the following
sequences to FOP's hyphenation
AAA,BBB,CCC,DDD
AAA1BBB2CCC3DDD
You don't get /any/ hyphenation points. The hyphenator gives up once
it encounters the first comma or digit. Maybe a similar thing is
happening with underscores... I'd have to check to say for certain
As for the hyphen character, that looks 'normal':
I don't think FOP currently takes into account anything else than a
specified "hyphenation-character" property, so changing that in the
en-US.xml file won't have any effect.
