 			This measurement is an approximation
 			(and in monospace fonts, an exact measure)
 			of a single <a href="http://unicode.org/reports/tr11/#Definitions">fullwidth</a> glyph’s <a>advance measure</a>,
 			thus allowing measurements based on an expected glyph count.
 
-			Note: The advance measure of a glyph can depend on writing-mode and text-orientation
-			as well as font settings, text-transform, and any other properties that affect glyph selection or orientation.
-
 			In the cases where it is impossible or impractical to determine the ideographic advance measure,
 			it must be assumed to be 1em.
