24.1 Introduction to the reference symbol combination

Link to a combination of characters - is an SGML construct that references a character from the document character set.

This version of HTML supports several sets of references to the combination of characters:

characters set ISO 8859-1 (Latin-1) In accordance with section 14 of [RFC1866] , a set of objects of the Latin-1 in this specification is extended to include the whole set of right side of the ISO-8859-1 (all code positions with the top level) including the widely used & nbsp ;, & copy; and & reg ;. The names of the combinations come from additions to of SGML (defined in [ISO8879] ).
symbols, mathematical symbols, and Greek letters . These symbols may be submitted font characters "Symbol" Adobe company.
significant markup characters and internationalization (eg, for bidirectional text).

The following sections provide comprehensive lists of references to the combination of symbols. Although the names of the agreement [ISO10646] are written in uppercase, we transformed them into the bottom for ease of reading.

24.2 References to ISO 8859-1 character sets

The links listed in this section to refer to the characters, numeric equivalents should already be supported by corresponding HTML 2.0 specification user agents. To access the division sign (÷) is much more convenient to use the link & divide ;, than & # 247 ;.

To support such combinations of named user agents need only recognize the names of objects and convert them into a set of characters [ISO88591] .

Glyph 65533 (FFFD hexadecimal code) is the last valid character set UCS-2. 65534 (hexadecimal code FFFE) is reserved as a version of the non-breaking space zero width with a permutation of bytes to determine the byte order. Glyph 65535 (FFFF hex code) has not been appointed.

24.3 Links to the characters, mathematical symbols, and Greek letters

The links listed in this section to refer to characters representing signs widely used Symbolfimry Adobe font, including Greek letters, various brackets and a number of mathematical operators such as gradient, product and amount.

To support these combinations of user agents must support the full set [ISO10646] or use other means. Displaying characters may be achieved through the ability to display the appropriate character set [ISO10646] or by other means, for example, an internal reflection on the listed characters, numeric character references in the appropriate position in some font that contains the requested characters.

When should you use Greek characters. This character set contains all the letters used in modern Greek. However, this does not include Greek punctuation, accented characters, and non-breaking stress (Tonos, dialitika) necessary for their preparation. Not including obsolete letters Coptic letters and letters polytonic Greek. Certain objects are not intended to represent modern Greek text; they are intended to represent the individual Greek letters used in mathematical papers.

24.4 Links to important symbols for marking and internationalization characters

This section lists the references to the symbols to indicate important to mark characters (the same as in HTML 2.0 and 3.2) to denote spaces or dashes. Другие символы в этом разделе относятся к вопросам интернационализации, таким как однозначность двунаправленного текста (см. раздел о двунаправленном тексте ).

Кроме того, добавлены комбинации для других символов кодировки CP-1252, не входящих в наборы HTMLlat1 или HTMLsymbol. Все они находятся в диапазоне от 128 до 159 в наборе cp-1252. Эти объекты позволяют определять символы независимо от платформы.

Для поддержки этих объектов агенты пользователей могут поддерживать весь [ISO10646] или использовать другие средства. Отображение знаков для этих символов может достигаться за счет возможности отображения соответствующих символов [ISO10646] другими средствами, например, за счет внутреннего отображения перечисленных объектов, числовых ссылок на символы и символов в соответствующие позиуии в каком-либо шрифте, содержащем необходимые знаки.
