It garbled as it has no japanese font

I can not input to file by Microsoft IME.
It garbled as it has no japanese fonts.

How can I add japanese fonts ?

(openSUSE Leap 42.2RC1)
(Nextcloud 10.0.1 (stable))
(docker collabora/code latest)

I solved it.(garbled)
I found new version.
(re pull and new run)

Regarding the support of Microsoft IME, this feature has not been implemented yet.
The latest collabora/code includes Google Noto fonts, which has the widest support of Unicode.
