Appendix F. ASCII Table

Gone are the days when ASCII meant just US-ASCII characters 0-127. For over a decade now, Latin-1 support (US-ASCII plus characters 160-255) has been the bare minimum for any Internet application, and support for Unicode (Latin-1 plus characters 256 and up) is becoming the rule more than the exception. Although a full Unicode character chart is a book on its own, this appendix lists all US-ASCII characters, plus all the Unicode characters that are common enough that the current HTML specification (4.01) defines a named entity for them.

Note that at time of this writing, not all browsers support all these characters, and not all users have installed the fonts needed to display some characters.

Also note that in HTML, XHTML, and XML, you can refer to any Unicode character regardless of whether it has a named entity (such as €) by using a decimal character reference such as € or a hexadecimal character reference such as € (note the leading x). See http://www.unicode.org/charts/ for a complete reference for Unicode characters.
