Having problem with typing in Korean

Hello.

a-Shell has been useful for me, but there is a problem yet to be fixed.

Korea input should construct a complete character with combination of a consonant and a vowel, optionally followed by one or two consonants.

For instance, a common greeting in Korean is “안녕하세요?“. However, whenever I try to type this in a-Shell, the input results in “ㅇㅏㄴㄴㅕㅇㅎㅏㅅㅔㅇㅛ?”

Would there be a way to fix this kind of input glitch?
