Failure of SC 1.3.5 due to using a non-text mark alone to convey information

Note: Glyphs are non-text marks.
This is insane. Unicode [6]defines glyph as:

1. An abstract form that represents one or more glyph images.
2. A synonym for glyph image. In displaying Unicode character data, one or more glyphs may be selected to depict a particular character.

In Web content, glyphs are text marks.

http://www.w3.org/WAI/GL/2006/07/10-wcag-teamc-minutes#item06 Michael to propose additional information about what glyphs are and are not, and what would be relevant to to this failure condition; Related issues: 780
(space separated ids); WG Notes: [TEAMC] [] From dictionary.com - glyph: 3. A symbol, such as a stylized figure or arrow on a public sign, that imparts information nonverbally. [Becky, Oct 9] an alternative proposal for the note: Font glyphs which impart information nonverbally are non-text marks. But I think a better solution is rewording the failure to avoid the use of the term, "non-text mark". <propose> Failure of SC 1.3.5 due to using a graphical symbol alone to convey information </propose> New resolution becomes: The definition of "glyph" includes representations of text characters and other symbols that represent information nonverbally. It was not the intention to exclude text representations. The title of the failure has been modified to refer instead to "graphical symbols" and the note has been removed. <michael's previous suggested response> Change note in http://www.w3.org/TR/UNDERSTANDING-WCAG20/Overview.html#content-structure-separation-understanding-58-head to read: Glyphs, other than renderings of <def>text</def>, are non-text marks. Respond with: The definition of "glyph" includes representations of text characters and other symbols that represent information nonverbally. It was not the intention to exclude text representations. Note has been clarified as follows: {@@<new wording} </end michael response> Discussed at Oct 9 team c meeting and agreed on response below. Discussed in the 19 October 2006 telecon: refer LC-780 and LC-797 back to Team C http://www.w3.org/WAI/GL/2006/10/19-wai-wcag-minutes.html Survey Results: http://www.w3.org/2002/09/wbs/35422/20061012-teamc/results <Andi> From wikipedia http://en.wikipedia.org/wiki/Glyph our meaning for a glyph can be defined as a "a typographical character that is a pictorial or decorative symbol" Could we just call it a "pictorial or decorative character symbol"? Proposed resolution (note that if accepted by Team C, LC-780 will have to be likewise modified and both included on the survey): </Andi> Discussed in the 25 January 2007 telecon: Resolution: close 780, 797 as proposed http://www.w3.org/WAI/GL/2007/01/25-wai-wcag-minutes.html {partial accept} DONE Remove "Note: Glyphs are non-text marks." from the Failure Techniques section of HTM 1.3.5. DONE Change title of F26 to "Failure of SC 1.3.5 due to using a graphical symbol alone to convey information" DONE Addressing Loretta's comments on the survey, update description in F26 to: The objective of this technique is to show how using a graphical symbol to convey information can make content difficult to comprehend. A graphical symbol may be an image, an image of text or a pictorial or decorative character symbol (glyph) which imparts information nonverbally. Examples of graphical symbols include an image of a red circle with a line through it, a "smiley" face, or a glyph which represents a checkmark, arrow, or other symbol but is not the Unicode character with that meaning. Assistive technology users may have difficulty determining the meaning of the graphical symbol. If a graphical symbol is used to convey information, provide an alternative using features of the technology or use a different mechanism that can be marked with an alternative to represent the graphical symbol. For example, an image with a text alternative can be used instead of the glyph. Internal WD updated 02 March 2007; Resolution: The definition of a "glyph" includes representations of text characters, punctuation, and pictorial and decorative character symbols. It was not the intention to exclude text representations. The title of the failure has been modified to refer instead to "graphical symbols", the note has been removed, and the description in F26 has been modified to clarify this point.; (Please make sure the resolution is adapted for public consumption)
