Hello all:

     I too have been looking for a standard set of icons.  Additionally, though, since I am blind I am really looking for a table that would be like:
description:code - that is, two text columns.
(e.g. trademark symbol:&#153)
I am unfamiliar with the methods to do this so probably confuse things.
There are "entities" in HTML such as &sup for superscript that JFW 4.01 reads very well (JFW says "superscript").
Apparently there is also unicode and SGML.  Is there a overview of the different kinds of icon representation methods that does not get too detailed about the inner workings of each character set.

Yep, 153 is the position in the windows character set. Its Unicode position 
is 0x2122 (or 8482 in decimal) so you can use &#x2122; or &#8482; 

You could also try &trade; though that depends more on browser support. 

AFAIR There is no character 153 (though I'm not too sure), hence the browser 
was able to realise you'd made a mistake and guess that you wanted the 
windows character of that position. 

(It's not an SGML thing as such, SGML uses character sets defined elsewhere, 
similarly with XML - and hence HTML since HTML has been XML for the last 3
