24.1 Introduction to character entity references

-A character entity reference is an SGML -construct that references a character of the document character set. - -

This version of HTML supports several sets of character entity -references: - -

ISO 8859-1 (Latin-1) characters In -accordance with section 14 of [RFC1866], the set of -Latin-1 entities has been extended by this specification to cover the -whole right part of ISO-8859-1 (all code positions with the high-order -bit set), including the already commonly used  , © -and ®. The names of the entities are taken from the appendices -of SGML (defined in [ISO8879]). -
symbols, mathematical symbols, and Greek letters. These -characters may be represented by glyphs in the Adobe font "Symbol". -
markup-significant and internationalization - characters (e.g., for bidirectional text). -

- -

The following sections present the complete lists of character -entity references. Although, by convention, [ISO10646] -the comments following each entry are usually written with uppercase -letters, we have converted them to lowercase in this specification -for reasons of readability. - - - -

24.2 Character entity references for ISO 8859-1 characters

- -

The character entity references in this section produce characters whose -numeric equivalents should already be supported by conforming HTML 2.0 -user agents. Thus, the character entity reference ÷ is a more -convenient form than ÷ for obtaining the division sign -(÷). - -

To support these named entities, user agents need only recognize the -entity names and convert them to characters that lie within the -repertoire of [ISO88591]. - - - - - -

Character 65533 (FFFD hexadecimal) is the last valid character in -UCS-2. 65534 (FFFE hexadecimal) is unassigned and reserved as the -byte-swapped version of ZERO WIDTH NON-BREAKING SPACE for byte-order -detection purposes. 65535 (FFFF hexadecimal) is unassigned. - -

24.3 Character entity references for symbols, mathematical symbols, -and Greek letters

- -

The character entity references in this section produce characters -that may be represented by glyphs in the widely available Adobe Symbol -font, including Greek characters, various bracketing symbols, and a -selection of mathematical operators such as gradient, product, and -summation symbols. - -

To support these entities, user agents may support full [ISO10646] or use -other means. Display of glyphs for these characters may be obtained by -being able to display the relevant [ISO10646] characters -or by other means, such as internally mapping the listed entities, -numeric character references, and characters to the appropriate -position in some font that contains the requisite glyphs. - -

-When to use Greek entities. -This entity set contains all the letters used in -modern Greek. However, it does not include Greek punctuation, -precomposed accented characters nor the non-spacing accents (tonos, -dialytika) required to compose them. There are no archaic letters, -Coptic-unique letters, or precomposed letters for Polytonic Greek. -The entities defined here are not intended for the -representation of modern Greek text and would not be an efficient -representation; rather, they are intended for occasional Greek letters -used in technical and mathematical works. -

24.4 Character entity references for markup-significant -and internationalization characters

- -

The character entity references in this section are for escaping -markup-significant characters (these are the same as those in HTML 2.0 -and 3.2), for denoting spaces and dashes. Other characters in this -section apply to internationalization issues such as the -disambiguation of bidirectional text (see the section on -bidirectional - text for details). - -

Entities have also been added for the remaining characters occurring in -CP-1252 which do not occur in the HTMLlat1 or HTMLsymbol entity sets. -These all occur in the 128 to 159 range within the cp-1252 charset. These -entities permit the characters to be denoted in a platform-independent -manner. - -
