Chinese Japanese Korean dynamic font

Hi, I have downloaded “Noto Sans SC” font from google font for the Chinese characters then I made a dynamic font asset for text mesh pro using (ctrl + shift + F12), it seemed to work fine
but the problem is NOT all characters displayed correctly and show the white box instead.
what I missed.

note: I take all the characters from the Glyphs table from the font itself (that means the font has already supported these characters)

Never mind I just figured it now just increase the Atlas height and width. just like the photo, the problem was that CJK characters are too much for 1024*1024 Atlas.
