Thanks for raising this issue. I am looking into it now.

On my system, I can see the Chinese characters in the console and they show up in the PDF.

The console output is likely related to the LOCALE not being UTF-8. My LOCALE is en_US.UTF-8.

Here is printed console output for me, with the grid showing the Chinese characters.

And the PDF is display is likely related to the system not having fonts that include the characters.
Here's a grid from my system that shows the Chinese characters.

My generated PDF has the following fonts embedded:

• DejaVuSans-Bold
• DejaVuSansMono
• DejaVuSerif
• NanumBarunGothic-YetHangul

The last font is Korean, but includes many Chinese characters. If I were to make a grid with some rare Chinese characters that don't show up in Korean, I'd probably get placeholders like the OP.
