ISSUE-429: Glyph vs code point in HRM

Glyph vs code point in HRM

Raised by:
Glenn Adams
Opened on:
The statement "Gr and Gc shall include only glyphs in presented regions and shall not include a [UNICODE] Code Point if it does not result in a change to presentation, e.g. the Code Point is ignored." is rather unusual in that it erroneously refers to glyphs in terms of a Unicode Code Point. Glyphs and glyphs codes are not directly related to Unicode code points. It would be better to say that a glyph that does not contain any renderable outline is ignored. But that is rather redundant since font designers do not include glyphs in fonts that do not have a renderable outline.
