Unicode characters missing in cfdocument pdf

I’ve been attempting to figure out why unicode characters aren’t showing up in my PDF on Lucee 6 on windows 2022. They are just blank. I can verify the Chinese chars in the HTML but the PDF is just blank. I’ve tried making a fonts.jar file with simsun.ttf in it with the proper line in pd4fonts.properties. I’ve tried doing various CSS ways to include the local files. I’ve tried doing font directory pointing at a font directly with the .ttf and the fonts.jar . so far no luck. Any other ideas I can try?

This is all with type=“modern” for cfdocument

I’m using fontembed="true" in the cfdocument

I’ve attempted using fontdirectory in two ways.

fontdirectory="D:\fonts"
fontdirectory="#expandPath('../fonts')#"

I’ve attempted putting the fonts.jar file in the following:

D:\Lucee\lib
D:\Lucee\jre\lib
D:\Lucee\tomcat\lucee-server\context\lib

I’ve tried putting the SimSun.tff here
D:\Lucee\tomcat\lucee-server\context\fonts

Anyone have any ideas on what I can try next or what I’m doing wrong? Thanks.
