Kanji is the language of Japan’s writing system which is used at a very massive scale in Japan for all kind of writings locally. With the application programming interface from the UPS which is integrated with any business’s official website, to let the users track their packages that are being shipped by that business models.
When it comes to API the kanji characters are not compatible with the API, which means the users can’t type their shipping or the delivery address in the Kanji character as the API from the UPS doesn’t support it.
The Japanese users have to convert the Kanji characters into the English language first, and then provide it as the address in the API to let the package be delivered at the right address.
