Japanese fonts available for Docviewer

[YamamuraK]

Most Japanese fonts on docx files are garbled when those files are opened in Docviewer.
Could anyone show the list of Japanese fonts that can be shown properly in Docviewer?
We found that Japanese characters written in MS-Mincho and MS P Gothic were not garbled, so we might recommend users to use it, but need reliable information about it.
Thank you.

As per servicenow support article the document has to be downloaded incase of Japanese language instead of directly viewing it on doc viewer.

Please refer the below article for more details:

Thanks for your answer.
We recognized downloading Word & PowerPoint files as the workaround.
But we are wondering if there is a certain list of fonts that are currently available in Docviewer, or any information that this issue will be fixed in the future version.
