In HTML2, these so-called<EM>character entities</EM> are limited to letters with accents and sometypographic symbols. HTML doesn't yet allow character entities for mathematicalsymbols and other common signs. Authors have to resort to inline images forthese. This document defines a list of some of those `other' symbols foruse in future versions of HTML.<H2> Contents</H2><OL> <LI> <A HREF="#introduction">Introduction</A> <LI> <A HREF="#rationale">Rationale</A> <LI> <A HREF="#standardized">What is standardized and what isn't?</A> <LI> <A HREF="#description">Detailed description of the entities</A> <LI> <A HREF="WD-wwwicn-960603.html#DTD">DTD fragment</A> <LI> <A HREF="#acknowledgements">Acknowledgments</A> <LI> <A HREF="#copyright">Copyright</A></OL><H2> <A NAME=introduction>Introduction</A></H2><P>HTML is a simple markup language for creating hypertext documents that areportable between platforms. A document that is marked-up with HTML consistsof a mix of data characters (the text that appears on the screen) and mark-up(information for the application about the function and relation of the variousdata parts).<P>Many data characters can be typed in directly: an `a' is just the `a' keyon the keyboard; for others the editor or word-processor may have a specialmethod to insert them: " + a = ä. If the editor doesn't offer such amethod, it may be possible to replace the character with a bit of mark-up:type the six characters `&auml;' instead of `ä' Any applicationthat understands HTML should be able to translate this back to the appropriatecharacter. A keyword like `&auml;' is called a <DFN>character entity</DFN>(or more precise: `character entity reference')<P>HTML2 defines a list of such character entities. That lists consists of allthe characters from the so-called <EM>ISO Added Latin 1</EM> set, plus afew of its own. This is enough for texts in most Western languages, but itdoesn't help with other languages or mathematics. It is expected that theset will be extended with all the characters in the ISO 10646 (a.k.a.<EM>Unicode</EM>) set, but even then there are many common symbols that aremissing.<H2> <A NAME=rationale>Rationale</A></H2><P>HTML documents often contain small icons to draw attention to interestinglinks or to special types of information. For example, the existence of asound could be indicated by an icon of a loudspeaker. Gopher and FTP menusalso use icons to indicate the types of links they contain.<P>Such icons could be created with inline images, but there are several advantagesto incorporating them into future levels of the HTML language in the formof SGML entities. In that way, they are defined on a par with other predefinedentities, such as the ISO-defined sets of accented characters or the mathematicaland Greek symbols.<P>One advantage is that authors do not have to hunt around for suitable imagesand create hyperlinks to them. Instead, they can write <TT>&audio;</TT>and be assured that all browsers will do their best to print some likenessof a loudspeaker.<P>Since the entity defines only the general shape, not the exact pixel-for-pixelimage, the browser is free to choose a size and color that matches the restof the display. The best browsers will have symbols in several sizes, appropriatefor use in 12, 14 or 17 point text, for example.<P>Using entities instead of inlined images is also faster (depending on theimplementation, of course). The browser will always use the same image foran entity, independent of the document's origin. After a while, there willeven be browsers that come with the symbols already built-in.<P>Authors are free to use any symbol for whatever purpose they choose, butlike Humpty Dumpty, they will be better understood if they do not make asymbol mean what they choose it to mean, but use it for its commonly acceptedvalue. The descriptions below suggest possible semantics, but only frequentusage by many people can make the true intention clear.<H2> <A NAME=standardized>What is standardized and what isn't?</A></H2><P>First of all, of course, the <EM>names</EM> of the entities are standardized.<P>Their intended use is also standardized, but the definitions are kept somewhatvague on purpose. As stated above, the meaning of a symbol is likely to evolvewhen it comes into common usage, until some universally accepted meaningemerges.<P>The shapes are <EM>not </EM>standardiazed, but the images in this documentare provided as suggestions, to give consistency across implementations.Developers of products on specific platforms are encouraged to use theconventional icons on that platform where they exist.<P>The alternative glyphs below are there mainly to show that the shapes<EM>can</EM> be varied.<H2> <A NAME=description>Detailed description of the entities</A></H2><P>Desriptions of the entites, with suggested renderings.
