• In Traditional Chinese, Japanese kyūjitai, Korean hanja and Vietnamese Hán Nôm, the component for this character is written with 廿 on top. Note that the bottom portion is written 口 overlapped by 夫 and not 中 on top of 天.
• In Japanese shinjitai, the component is written either with ⺾ (3 strokes) on top and has one stroke less. Due to Han unification, both traditional Chinese and Japanese shinjitai forms are encoded under the same code point. The appearance of this character will differ depending on the font used.
• In Simplified Chinese, the component is simplified to 又 instead, giving the character 叹 (U+53F9).
• Two compatibility ideographs exist for this character. U+FA37 corresponds to the kyūjitai form of this character while U+2F84C is an alternative form used in Taiwan and North Korea which is similar to Japanese shinjitai but the top right component is written ⺿ (4 strokes) instead of ⺾ (3 strokes).
