Overview
The “Historiographical Institute Database Variant Character Identification List” is published on the following page.
https://wwwap.hi.u-tokyo.ac.jp/ships/itaiji_list.jsp
This time, I will create an API to retrieve the data published on the above page in JSON format.
What Was Developed
You can access it from the following URL.
It returns a mapping using “char (variant character)” from the identification list as the key and the “base” kanji as the value.
Summary
I hope this serves as a useful reference for applying variant character lists.
