Wikimedia migrated from Bugzilla to Phabricator. Bug reports are handled in Wikimedia Phabricator.

See the source code of this page:

http://en.wikipedia.org/wiki/Lucida

Try to edit it. Compare that Wiki-code to final HTML- and CSS-code that goes to
WWW-browser. I just can not define font families with spaces in their names,
when I use style-attribute in P-tag.

Let's see...
<p style="font-family: "Lucida Sans Unicode", "Lucida Sans", "Lucida 
Grande", LucidaSans, Lucida, monospace; padding-left: 
3em;">{{Lipsum}}</p>

Your code is invalid. Take a look at this section of the HTML spec:
