Issue Summary

Japanese IME is not working properly in Assets "Text area" attributes.
When using Japanese IME Romaji input, users need to convert the alphabet to Japanese character.
If entering the text "テスト" in Japanese, we need to type "tesuto".

Currently, "Text area" attributes does not allow this conversion.
