Hi. I found the following when trying to learn if there is such a thing as a
non-breaking hyphen. Apparently Unicode has a ‑ but that is not
well-supported, especially in older browsers. Somebody somewhere said:
Alternately, you can use CSS to declare a class having:
..nowrap { white-space:nowrap }
.... and then wrap the compound word in a <span class=nowrap></span> tag (or
any other suitable inline tag). You can also try { white-space:pre } ...
I wasn't sure where to post this, because part of the question is about the
character entity that apparently is NOT defined in html? However, what about
the CSS idea for non-wrapping? On one of my pages www.TheBicyclingGuitarist.net/newstuff.htm I give credit to some folks at
comp.infosystem s. www.authoring.site-design. I want the hyphen in between
site and design to be a non-breaking one.

You can do that. There are other solutions. I use <nobr>the stuff that has

<nobr> is not a valid element in HTML4.01. If you get bugged by this

Using CSS white-space:nowrap seems to work well in browsers that are at
all recent. There is however a small confusion factor: the CSS2 spec
says that white-space only applies to block-level elements. For
white-space:pre this is sensible, for white-space:nowrap it is stupid.
But the browser writers seem to have decided to ignore that line of the
spec and do something sensible. (AFAIK)

Yes, when CSS is enabled.

It has long been said that this was a mistake and they probably didn't
mean to say so. But due to the processes of the W3C, the W3C
recommendation is currently the CSS2 spec but the W3C really _means_ that
everyone should use the CSS 2.1 draft ("Proposed Recommendation" ).
The wording of the meaning of the property is vague too, especially if
you think about the name white-space. Hyphens aren't white space of
course.

The construct ‑ is certainly defined in HTML, as denoting the
character NON-BREAKING HYPHEN U+2011. (It's not a character entity but a
character reference. The terminology seems to be permanently confused,
though.)
But the HTML specifications are very vague about the required processing
of characters. Surely U+2011 has definite semantics in Unicode, but are
HTML user agents required to observe all the semantics of Unicode
characters? The HTML specifications says, oddly:
"In HTML, there are two types of hyphens: the plain hyphen and the soft
hyphen." http://www.w3.org/TR/html4/struct/text.html#hyphenation
Later it specifies that "plain hyphen" means U+002D, or the well-known
"Ascii hyphen", or HYPHEN-MINUS to use the Unicode name. This character
has, by Unicode definition, ambiguous semantics, as its official Unicode
name suggests.
So apparently the real hyphen, HYPHEN U+2010, is _not_ a hyphen in HTML,
and neither is the non-breaking hyphen. Right? Or maybe not. Maybe the
people who wrote the HTML specification simply didn't think much about
character semantics in general. They just wrote a short, sketchy, and
misleading description that revolves around the soft hyphen (and mentions
"plain hyphen" just for contrast).
Hence, the fact that few browsers support the non-breaking hyphen cannot
really be regarded as bug. Moreover, it's basically a _font_ issue. To
satisfy minimal requirements in processing (as far as rendering HTML
documents goes), a browser simply has to display the character, treating
it as a normal graphic character (as opposite to its eventual treatment
of "plain hyphen" as allowing a line break after it).

You noticed that too...

processing of characters. Surely U+2011 has definite semantics in
Unicode, but are HTML user agents required to observe all the
semantics of Unicode characters?
I think the answer to that is "not entirely". There are some Unicode
rules that are intended to be effective in plain text, but don't have
any obvious applicability in the source "code" for a markup language,
for example.
The HTML specifications says, oddly:
"In HTML, there are two types of hyphens: the plain hyphen and the soft
hyphen."
http://www.w3.org/TR/html4/struct/text.html#hyphenation
This goes right back to RFC1866, doesn't it? And has not been taken
seriously by browser implementers.
Later it specifies that "plain hyphen" means U+002D, or the well-known
"Ascii hyphen", or HYPHEN-MINUS to use the Unicode name. This character
has, by Unicode definition, ambiguous semantics, as its official Unicode
name suggests.
RFC2070 referred to iso-10646 rather than Unicode as such, but
developments have really made that distinction rather irrelevant. At
least, we might hope that they have.
So apparently the real hyphen, HYPHEN U+2010, is _not_ a hyphen in HTML,
and neither is the non-breaking hyphen. Right? Or maybe not. Maybe the
people who wrote the HTML specification simply didn't think much about
character semantics in general.
You could put it that way...
Hence, the fact that few browsers support the non-breaking hyphen
cannot really be regarded as bug.
And, conversely, that authors cannot really *rely* on browser
behaviour in this regard.

Surely they don't have any applicability in any text except as the
application chooses them to have applicability.
If you use vi to create a unicode readme file that contains arabic
characters then would a programmer cat'ing the file to the console expect
to see the arabic going left to right or right to left? (Assuming the
console knew how to handle the character-encoding/character-set in the
first place).
If an html file containing mostly english text includes a paragraph that
uses characters in the range U+0600 through U+06FF (arabic) then should
the browser be "smart enough" to display this right to left?
Somehow, having the browser recognize different characters as being
different kinds of hyphens and therefore formatting the text differently,
instead of requiring markup to tell it what to do, seems wrong to me but
that's just my spur of the moment $0.02 worth.

You should *never* use <nobr> under any circumstances in HTML, even if
you write your own DTD. It is a presentational element, and thus has no
place in HTML. It is also a proprietary element created by either
Netscape or IE (I can't remember which), which makes it even worse.
You should use semantic class names that represent what the content is,
not how it looks. When writing markup, you have to think about *why*
the content needs to have no breaks, or other presentational features,
not what it looks like. For example, from The Bicycling Guitarist's
page, where (s)he would like the it to not wrap, in the following:
comp.infosystem s. www.authoring.site-design
Usually, I would recommend using the U+2011 (‑, ‑ or ‑),
though apparently support in older browsers is an issue, but more
importantly, because it is the name of a news group which uses a
HYPHEN-MINUS, and that name needs to be understood if it were copied and
pasted into a news reader. Thus, the use of a non-breaking hyphen is
actually incorrect. I tested this, and wrote that newsgroup using a
non-breaking hyphen, and then copied to my newsreader. The group could
not be found, but once I chaged it back to a regular hyphen it worked.
Therefore, in this case, it appears that the use of a non-breaking
hyphen is infact presentational, not semantic, so I would markup that up
like this:
<a href="news:comp .infosystems.ww w.authoring.sit e-design"
class="news">co mp.infosystems. www.authoring.s ite-design</a>
That has the advantage of also providing a link that a user can use to
subscribe to the newsgroup.
Because it is also code that can be used by a news reader to subscribe
to that newsgroup, then you could also markup it up in <code>, or even
<kbd> depending on the context, but <kbd> would only be appropriate if
you were telling a reader to enter the text into their newsreader. In
this case, <code> seems most approprate.
<code class="news">co mp.infosystems. www.authoring.s ite-design</code>
If you like, you can also combine both the link and <code>, but only one
needs to have the class="news".
Finally, just apply the style to .news { ... }

class="nobreak" is just as bad as <nobr> in my opinion, it says nothing
about *why* it is being styled like that. The only difference is that
at least the span is valid, so I would always choose that over nobr, but
since they're rarely, if ever, the only options, I would always use
something more semantic.
I hate CSS-soup as much as I hate tag-soup.
Using <nobr> is tag soup, so that's just being hypocritical. Although
I've never heard of CSS-soup before, but I'm guessing, if you didn't
just make it up, that it would refer to CSS filled with presentational
class names and IDs (Which I've seen plenty of), rather than styles for
semantic elements, classes and IDs, which is i how stylesheets should be
done.
