My wife has a 2019 MacBook Air running Catalina with Acrobat Reader 2022.003.20281. With this machine she is able to fill forms using a Thai font:
She also has an M1 iMac running Ventura with Reader 2022.003.20281. With this machine when she enters Thai text it comes out as garbage:
Oddly, Reader seems to "know" what to display, it just doesn't know how to do it:
We do have "Use local fonts" enabled in the Display preferences and both machines have the same Thai fonts installed.
Any ideas on how to fix this?
Never mind. It turns out that Reader had been updated without updating the font packs.
