Character corruption of metadata

I have tried to show the metadata of Japanese 3DTiles Data.
However I got a character corruption like a picture below.
I just followed the tutorial here.
If there are something that I miss, would you please give me an advise?

Hello @w.yasuda ,

Thanks for reporting this, I opened a GitHub issue here. I think my observation in the GH issue may be the cause for the problems you are encountering, but we’ll have to test it out to make sure.
