[1] In China and Hong Kong, the emphasis mark (Chinese: 着重号) is used in textbooks and teaching materials.
In Japan, the emphasis mark (傍点 bōten or 圏点 kenten) is usually a dot or a sesame dot and is centred above each character in the horizontal texts and to the right of each character in the vertical texts.
It is not unusual for kenten and ruby to concur on the same side of the main text (usually above or to the right), but this feature has not been possible with CSS.
In South Korea, the emphasis mark (드러냄표 deureonaempyo) usually rules as a dot or circle centred above the characters in the horizontal texts and to the right of the characters in the vertical texts.
After Vietnam switched to the Latin alphabet, emphasis marks fell into disuse as bolding, underlining, and italics replaced the usage of emphasis marks.
