Hanja Converter is an Android app designed to facilitate typing in Hanja characters using your existing keyboard. This utility tool supports both Hanja-word and character-wise conversion, offering users the flexibility of two customizable candidates windows. It is important to note that the app utilizes Accessibility Service for its main functionality, such as extracting content to convert to Hanja and replacing user-entered text with Hanja characters. The developer ensures that user-entered content is not collected or used for any other purposes. In case of compatibility issues with certain apps, users can resort to copying and pasting text from supported applications. Remember to open the app post-installation for the initial set-up process.
