When processing multilingual text, encoding issues with Chinese, Japanese, and Korean (CJK) characters often lead to garbled text or display anomalies. This tool provides precise bidirectional conversion between CJK characters and code points using the Unicode standard. A single code point (e.g., U+4F60) corresponds to a basic unit of an ideograph, supporting the conversion of character sets like Hanzi, Kana, and Hangul.
Q: What are the Unicode code points for "你好"?
U+4F60 U+597D. These are the standard code points for the two Chinese characters "你" and "好" in the Unicode Basic Multilingual Plane (BMP).
Q: Does the tool support rare Chinese characters in the extension blocks?
It supports all CJK Unified Ideographs within the BMP, including Extension A characters. However, the validity of code points for some rarely used characters in Extensions B-F may need to be verified.
We recommend processing no more than 500 characters at a time. Non-Unicode encodings (such as GB2312) must be converted to UTF-8 first. The conversion results do not include character property metadata.
When handling CJK text in development, it is highly recommended to use the standard U+XXXX format. For example, the Japanese word "日本語" can be converted to U+65E5 U+672C U+8A9E. This format is universal and highly readable across most programming languages. Note that UTF-8 encoding and Unicode code points are different concepts—the former is a byte sequence, while the latter is an abstract character number.
