HTML 1.0 assumes a character set for transmission to be ISO8859 (Latin-1). This includes 256 characters; the first 128 coincide with ASCII 7-bit. The others may be represented in several ways. Here we list, for each character,

1. its ordinal number in decimal
2. the same number, in octal (e.g. the Unix command to change "¡" to "!" would be "cat filename | tr \241 \041"
3. the same number, in hexadecimal (e.g. an extended URL might include the string "%A1" to transmit the character "¡"; a MIME encoding would be "=A1")
4. a single 8-bit character (as stored in European documents, say)
5. the HTML "entity name" for the character (e.g. we enter the ASCII string "¡" into the HTML files at this site to render a "¡")
6. the rendering of that HTML entity (if your browser is HTML 1.0 compliant, this should be e.g. an inverted exclamation mark. For most browsers, this will appear identical to the character two columns earlier.)

In these pages we use none of the non-printing characters (&#001 or ctrl-A, etc.) except line-feeds (&#010; or ctrl-J) and spaces (&#032;) -- in particular we do not use tabs (&#009; or ctrl-I) or carriage-returns (&#013; or ctrl-M). Since the ampersand (&), less-than (<), and greater-than (>) characters have special meaning in HTML files, we encode them using entity names, too: "&amp;", "&lt;", and "&gt;", respectively. Finally, we avoid dollar-signs "$" to avoid a possible conflict with TeX encodings; when the symbol is needed, we use the decimal HTML code "&#036" since for some reason the entity code "&dollar;" is not recognized here.

The printing ASCII characters are those with (decimal) ordinals 33 "!" to 126 "~". Character numbers 127 through 159 are unassigned (but see below); the rest of the HTML 1.0 character set is as follows:

Although HTML1.0 does not specify a character to be rendered for decimal codes 127-159, a few of those codes are treated consistently by a number of recent browsers; they are shown below. (This is primarily a Microsoft convention.) Please note that since these characters are neither specified by standard nor universally recognized by browsers, they are not used in these documents. They are simply listed below for your experimentation! (the last column is rendered with e.g. "&#128;", etc., since entity codes are not available.)

HTML 1.0 uses the ISO8859 character set as the medium of data exchange. For background information on this decision see (http://www.uni-passau.de/~ramsch/iso8859-1.html). For more information visit htmlgoodies.com and search under "character set" You can view other tables of ISO characters by decimal number (http://ucs.orst.edu/~ramsperg/framed_iso.html) or entity name (http://www.htmlgoodies.com/tutors/&command.html)

HTML 4.0 will use the Universal Character Set (UCS) as its character set; UCS is a character-by-character equivalent to Unicode 2.0. Unfortunately, most browsers are not yet ready to display these characters. For more information and a few of the "next generation" characters, see
http://www.natural-innovations.com/boo/doc-charset.html
To really whet your appetite for the symbols which will be available for web documents once this standard is widely accepted, look at the Unicode charts at http://charts.unicode.org/charts.html.
