Phssthpok · 09-03-2015, 08:14 AM

If I have a list of items separated by slashes, first/second/third, I want to be able to allow line breaks after a slash. The zero-width space and zero-width non-joiner characters both seem like good candidates.

According to the Unicode spec, the zero-width space "is not a visible separation, but it may expand in passages that are fully justified." However, it seems that the same is true of the ZWNJ as well (at least on the Kindle), which also shows up as a visible space between characters in justified text.

Is this another Kindle rendering bug, or is it normal behaviour? If it's normal behaviour, is there something else I could use that it guaranteed never to be expanded into a space in justified text (i.e. a "soft line break" character)?
