Japanese characters are not displayed in PDF

I find this service yesterday, and tried free plan. but only Japanese characters are not displayed in PDF.(preview, download,e-mail attouched)

So I found this thread, looking for ways to solve it. (https://www.invoiceninja.com/forums/topic/3-5-1-japanese-characters-are-corrupted-in-pdf/)

so I installed self-hosted version(3.7) on my Rental Server.
But the results were the same.

characters are not displayed in chrome safari IE , but in firefox it was cropped.
I want to know how I can fix it.

sorry my terrible english!!

Can you check you’re using a Japanese font on /settings/invoice_design

!!! I missed it!! it’s so basic setting…
Now I can see all PDF in Japanese! thank you so much!!

Great to hear, thanks for letting us know!
