Thanks for your fast reply!

Yes, but there is no line-break. As far as I understand ­ should be a hint to the text-layouting engine that this place can either break (using a -) or ignore it (and not rendering the char at all).

But it looks like PD4ML doesn’t support that. Is there an easy way to implement something similar/like that?

– is it possible to somehow query/ask the rendering system if it overflows in that particular div? (I guess not)
– is there way to not overflow at all? Just add a linebreak after the last possible character in a div?
– would it be possible to add an ‘optional’ zero-width linebreak?
