Proposed definitions to address issue 673 [1]. Notes and references at [2]. These definitions are not perfect, but lay the basis for tomorrow's teleconference discussion about Unicode and text. text A sequence of characters included in the Unicode character set. Refer to Characters [3] in Extensible Markup Language (XML) 1.0 (Third Edition) for more specific information about the accepted character range. Unicode In this document, we use "Unicode" to refer to the Unicode character set and not the character encoding. (@@ the Unicode character set may be encoded in ASCII, UTF-8, UTF-16, etc. characters in the Unicode set can be created with numeric character references - so there is a clear separation between the character encoding and those characters defined in the unicode character set that we consider "text"- @@provide reference to I18N list? @@link to Unicode spec?) non-text content Non-text content is content that can not be represented by a Unicode character or sequence of unicode characters. Non-text content includes but is not limited to * images and graphics, * sound clips, movies, and animations, * ASCII art (which may use several Unicode characters to create an image) Providing text alternatives for non-text content is addressed in Guideline 1.1, providing captions and audio descriptions of multimedia is addressed in guideline 1.2, and interacting with non-text content via scripts, applets, and programmatic objects is addressed in guideline 4.2 .
