When I choose an Asian character set, such as Japanese or Chinese, on a SB3 I see the community-supported translation for Japanese or Chinese.

For example, on Boom, when I select Chinese:

Now Playing = Bo Fang Zhong
Music Library = Music Library
Favorites = Hu Lian Wang Shou Yin Ji
Music Services = Music Services

On an SB3, Music Library and Music Services are seen as not translated, so that's OK. On an SB3, Now Playing and Favorites display Chinese characters.
