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 corresponding 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 Search the Unihan Database page supports queries against several properties, such as those for ideograph readings. The following two indices are also available:
For access to the latest version of the data files that comprise the Unihan database, download and unzip the Unihan.zip file from the UCD (Unicode Character Database). The Unihan database and its properties are documented in UAX #38.
