The Unicode standard assigns a unique code point to each character, allowing for consistent representation and processing across different software and platforms. The U+4E00 to U+9FFF range covers ideographs that are fundamental to written communication in Chinese, Japanese, and Korean. This extensive block is crucial for digital text processing, enabling the accurate display and manipulation of these complex logographic characters. It is one of the largest blocks within the Unicode standard.
