Subject: size-unit glyph -- revisited
I'm now wondering if glyph is the right word that represents what we have in mind. The sequence of characters "fi", for example, sometimes are ligated and displayed in one glyph. Whether they are ligated or not depends on the font and the rendering engine. So the number of glyph cannot be determined unless we know the environment in which the string is displayed. On top of that, we most likely don't want to count "fi" as one size-unit. I think that what we want to designate using "glyph" is something a regular user thinks as a "character". In that case, a unit called "grapheme cluster" Unicode consortium defines [1] may be more appropriate.
