Kinsoku, anyone?

I should admit that I am a little rusty as my last post was a while ago.

I am interested to find out what content providers do to avoid Japanese Kinsoku issues. This page has a lot of details, but apart from specifying line-break="strict", are there any other known solutions that the Japanese web sites employ to minimize the problem? Ideally, I would like to know if anyone is using ZERO WIDTH NO-BREAK SPACE (U+FEFF), ZERO WIDTH SPACE (U+200B), or WORD JOINER (U+2060) to work around this issue.
