For you web developers, this should explain one of the biggest misteries in web developement.
Or maybe someone taught you that once, or you weren’t as stupid as I am, removing all those seemingly uneccessary non-breaking spaces in my Government’s web site…

So, this:

<p>Blabla « W3C » etc. whatever</p>

On a narrow page gives this:

Blabla « W3C
» etc.
whatever

This:

<p>Blabla «&nbsp;W3C&nbsp;» etc. whatever</p>

On the same narrow page gives this:

Blabla
« W3C » etc.
whatever

Yes, &nbsp;, or non-breaking spaces, concatenate whatever you put with it in one word, making the word wrapping of a citation correct. (Yes, &nbsp; are not only used to make an empty table square appear in IE)
