Custom line breaking algorithm

Hi,

We are working on an upgrade to fop 2.2 from a very old version.

Unfortunately we ran into the issue were text is overflowing in table columns as in the attachment.

In the older version of fop that we used we have the following algorithm:


-          If the word is too long to fit on the line, move it to the next line

-          If the word is too large to fit into the column break the word

We cannot make use of hyphenation because multiple languages are combined in one pdf and we are not aware of the language.

The only way we think we can implement this is to adjust the line breaking Knuth algorithm in the implementation.

Would this be the right approach ? Has any one done this before ? Can someone provide some guidance on this ?

Many thanks in advance,

Kind Regards,

Ronny

All,
 
   I don't really develop in FOP, but I use it extensively.  Would there be a way to specify a character other that a space that would be used to word break?

Hi,
 
You could add a zero width space inside your url to break it:

Thanks for the answer. 
 
But using a hypenation list would be very hard I think since we do not know the language the document contains.
 
Can you elaborate on how you would approach this ?
 
Thanks

Hi,
 
Why not make your own hyphenation word list.
 
Thanks
