U+6B25 "欥" CJK Unified Ideograph-# Unicode Character
U+6B25 "欥" CJK Unified Ideograph-# is a rare and largely obsolete Chinese character that historically functioned as a variant form of the character 歎 (tàn), meaning to sigh or to exclaim. It is composed of the radical 欠 (qiàn), which relates to the mouth or breath and signifies an action involving the mouth, paired with the phonetic component 日 (rì), meaning sun. In classical texts, this character appears infrequently, primarily as an alternative graphical representation in ancient or variant character sets, and it has no common modern usage in standard Mandarin or contemporary writing systems. As part of the CJK Unified Ideographs block, it represents a historical linguistic artifact that is now rarely seen outside of specialized philological or digital encoding contexts.
