CJK Unified Ideographs

CJK Unified Ideographs is a block of the Unicode standard that contains the most commonly used characters for writing Chinese, Japanese, and Korean. It is the largest block of the Unicode standard in terms of the number of characters it contains, with over 20,000 characters. This block includes all the characters needed to write the majority of Chinese, Japanese, and Korean text, including both simplified and traditional characters. It is often used in conjunction with other blocks, such as CJK Unified Ideographs Extension A and B, to fully support these languages in text processing and display applications.
