I'm not clear what you're asking me.  HTML5 defines at least two
different types of whitespace: what it calls "space characters" (0x9,
0xa, 0xc, 0xd, 0x20), and what it calls "White_Space characters"
(Unicode characters with the White_Space property).  See
<http://www.whatwg.org/specs/web-apps/current-work/multipage/common-microsyntaxes.html#space-character>.
 The two types of whitespace are treated differently in some ways by
the standard.  For instance, "a set of space-separated tokens"
<http://www.whatwg.org/specs/web-apps/current-work/multipage/common-microsyntaxes.html#set-of-space-separated-tokens>
count only "space characters", not "White_Space characters", as space.
