About the Unihan Database Lookup Tool

The lookup interface on this page provides online access to property data in the Unicode Han (Unihan) database for individual ideographs via the “Lookup” button and text field above. Simply enter the four- or five-digit hexadecimal code point for the desired ideograph into the text field, or copy and paste the ideograph into it, then click the “Lookup” button. The resulting data set will contain various types of information available in the Unihan database, such as mappings to legacy encoding standards, references to dictionaries, meaning and reading information according to various authorities, links to other websites, and so on.

If you do not know the code point of the ideograph, or have no example of the ideograph to copy, the Unihan Search Page supports queries against several properties, such as those for ideograph readings. The following two indices are also available:

For production reasons, the version of the Unihan database that is available on this page may not yet be synchronized with the latest version of the Unicode Standard.

The Unihan database and its properties are documented in UAX #38.
