Windows users have an increasing range of Unicode fonts, some for specific languages and others (such as Arial Unicode MS, Bitstream CyberBit and Code2000) covering many languages and scripts. Web browsers should be able to utilise more than one font for displaying a page that contains special characters or multiple scripts, by relying on their defaults or on the user’s preferences – it is rarely necessary for the author of a page to specify fonts. Editors should ideally be able to utilise more than one font for a single HTML document. Fonts for specific languages tend to give results that are more acceptable to native speakers than fonts that try to cover many languages and scripts. Unicode fonts allow complete character sets for several languages to be held within a single font file, but they do not need to contain all of the Unicode characters. If you want to add text in other scripts to your HTML pages, it would obviously be time-consuming and error-prone to type many numeric character references, so you need to use either an HTML editor with multilingual support, or a word processor that has multilingual support and the ability to save files as HTML with UTF-8 character encoding. Netscape Communicator 4.x only recognises a few hexadecimal character references. Any Unicode character can be entered using this method. For example, - should display as an em dash (-). If you prefer to use hexadecimal numbers instead of decimal ones, you can do so by adding an ampersand, a hash and an x at the front and a semi-colon at the end. Netscape Communicator 4.x cannot display most numeric character references unless they are present in the document’s character encoding. Numeric character references are supposed to be displayed independently of the document’s character encoding, and so should work in HTML files with any character encoding. This is the method used in the Unicode test pages. You can enter any Unicode character in an HTML file by taking its decimal numeric character reference and adding an ampersand and a hash at the front and a semi-colon at the end, for example - should display as an em dash (-). Netscape Communicator 4.x cannot display most of these entities unless they are present in the document’s character encoding. These character entity references are supposed to be displayed independently of the document’s character encoding, and so should work in HTML files with any character encoding. There are 252 characters that can be included in an HTML file by typing a symbolic name between an ampersand and a semicolon, for example - for an em dash (-). If you only want to use a few Unicode characters that are not on your keyboard, for example mathematical symbols or a few characters in a different script, there are three ways of entering these characters into your text. Recent versions of Internet Explorer go even further, with support for Mongolian, which is written top-to-bottom. RFC 2070 ( Internationalization of the Hypertext Markup Language) has also been incorporated into HTML 4.0, which now includes provision for languages that are written right-to-left (such as Arabic and Hebrew), for appropriate punctuation, and for combining of letters and diacritics. The UCS as specified in ISO/IEC 10646-1:2000 is precisely equivalent to the Unicode Standard 3.0. The HTML 4.0 Specification made a major step towards internationalizing the World Wide Web by adopting the Universal Character Set (as specified in ISO/IEC 10646 Information Technology - Universal Multiple-Octet Coded Character Set (UCS)) as the document character set for HTML. It is therefore ideally suited to the World Wide Web. Unicode is designed to allow single documents to contain characters or text from many scripts and languages, and to allow those documents to be used on computers with operating systems in any language and still remain intelligible.
