Meet Dr.Stockton :-) In many posts (no matter what the subject is) he
likes to state between the lines that:
1) He was the one holding paper bands (variant: giving final advises to
Vinton Serf) during the first ARPANET test run.
2) Everything what the Internet is staying on was invented in the
United Kingdom and only later adopted or (mostly) stolen by the US.

IMHO both statements are rather mutually exclusive but somehow he
manages to put it all together, sometimes in one line.

Under further thinking (and after he said that it was not about
DIN-like combo  sets) I see the only one option left:

He must be talking about BS 4730 : "Specification for the United
Kingdom 7-bit data code
(ISO-7-UK)". This is the exact copy of (US-)ASCII the UK adopted for
luck of their own but the British militaries insisted to call it
somehow without that humiliating "A" in the acronym :-)
There never was any ISO standard for that, the "ISO" part in the name
is an "ears-pleasing" bogus.
BS 4730 is registered as international standard ISO/IEC 646:1991
I leave for you to find and to read the rest.

The only purpose to drag that "ISO-7 coding" into post was in
expectation of a question like
   - what is ISO-7 coding?
so then to answer
   - you are too young to remember... my poor child
and if anyone asks
   - so it's ASCII then?
then to answer
   - NO, our ORIGINAL British ISO-7 coding.

Dr.Stockton... That explains a lot :-)

Sorry, but yours. If you start your sentence with "Unicode" then use
Unicode names. Or just say "I know HTML entity for ... but what would
it be for ..."

I have a printed Internet copy of X-files about the aliens conspiracy.
Would be any quote of it obvious to others? :-)

So by getting the Albionic fog out "possibly visible as ...
"plus/minus", in ISO-7 coding" means to say "possibly emulated in ASCII
as +/- character sequence w/o spaces". OK... However it's said - most
importantly we've finally got it.

So did you come for help or just to complain and to show up a bit?

And _you_ have very conveniently snipped off the part where the OP said
(in effect) "however, I need a -/+ symbol"...

Not really. They're more convincing for showing what works on your
browser, on your operating system, with your screen size and window
size, with your particular set of installed fonts, ...

And, from the point of view of practical authoring, is a necessary
condition.  I don't wish to insert a coding seen in non-HTML and find
that I cannot read the character in HTML here.

I use XP sp2 MS IE and a composing window set by

    <BODY onLoad="window.resizeTo(640, window.screen.height*0.9)">

Therefore, ISTM that the vast majority of normal users, even with
different systems, will see much the same as I do (though doubtless some
of those here will have among their systems one or more where that does
not hold).  Remember the nature & topics of my site.

So mine is a condition presently sufficient in practice.

If, for example, there are problems found by users of RNIB-recommended
software, I will look to them/RNIB to tell me and to the RNIB for
skilled advice.  Unhappily, the nearest to an RNIB-type that I've seen
in News is an RNID-type - most helpful, but moved on now : and B != D.

It's good to read news:comp.lang.javascript and its old FAQ. See below.

If Opera and Mozilla can render it, the glyph is obviously available on
the system; it's not a stand-alone problem, IE < 7 simply doesn't look
any further than you explicitly ask, so Andreas’ reply is quite right.

IE 6 cooperates over here with Lucida Sans Unicode (shipped with XP Pro
SP2 at my end, FWIW local versions may differ; Arial Unicode MS is
another likely candidate – for those who have M$ Office installed).

I have a font named cmsy10.ttf that contains the minus-plus symbol.
Using escape sequences (alt-0nnn), it's at alt-0168.  Plus-minus is at
alt-0167.  These escape sequences, of course, are not in compliance with
the W3C specifications.

I don't know where I got this font.  It's with several others named
cmex10.ttf, cmmi10.ttf, and cmr10.ttf.  While I have these, they are not

They are most likely TTF versions of the TeX Computer Modern fonts
designed by Knuth.  The names match (bar the extension).
