When Japanese stored in Shift_JIS encoding is opened in the EUC-KR environment, characters appear as writhing characters such as "Wonderful", and the characters are broken.

It is an app that converts the broken Japanese (Bun) back to before it was broken and then translates it into Korean, or translates the Korean into Japanese and breaks it into parts and converts it into Bun.
If you press and hold the button to change the word to Korean, it will change to Japanese, and if you press and hold the button to change the word from Korean to the word, it assumes that the input is Japanese and changes it to the word.
