U+6537 "攷" CJK Unified Ideograph-# Unicode Character
U+6537 "攷" CJK Unified Ideograph-# is a Chinese character that primarily means "to examine," "to test," or "to verify," and it is historically related to the concept of textual criticism or collation. In classical Chinese, it often appears in scholarly contexts, such as in the phrase "攷證" (kǎozhèng), which refers to the process of verifying evidence or conducting research. The character is composed of the radical "攴" (pū), meaning "to strike" or "to tap," suggesting an original action of checking or examining carefully, and it is considered a variant or alternative form of the more common character "考" (kǎo). While less frequently used in modern standard Mandarin, "攷" retains its significance in historical texts, linguistics, and certain technical domains where precise examination or authentication is emphasized.
