The ­ unicode characters were added after a number of very long URLs were posted and broke the layout of certain long posts (notably the "lists of" links).
Because there is no internal space in a URL no amount of telling CSS to wrap text worked. The only solution was to add a form of zero-width whitespace that would allow browsers to wrap a long and solid URL at certain points. We add a ­ every 25 chars so that the browser width can be used to wrap at the appropriate point.
As you point out, clicking the link and following the href still works. In fact, the href is the only thing we will ever guarantee to work.
Ah right... yes, that is international.
And as you say... clicking on the link works.
