U+5B57 "字" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
字
U+5B57 "字" CJK Unified Ideograph-# is a Chinese character that fundamentally means "character," "word," or "letter," and it is commonly used in East Asian languages including Chinese, Japanese, and Korean. This ideograph originates from ancient pictographs, combining a roof radical (宀) over a child radical (子), symbolizing the nurturing or birthing of written symbols within a home or place of learning. As a core component of the written language, "字" appears in countless compound words, such as "汉字" for Chinese characters, "字母" for alphabet, and "字典" for dictionary, reflecting its essential role in literacy and communication across East Asian cultures.
