I have staff using Acrobat 9 Pro to do commenting & markup of CAD files. They enter text in Comment and Callout boxes in English and Chinese (due to the nature of the project). What we've discovered is that any Callout boxes that have both languages in them or perhaps only Chinese in them display as empty or blank Callout boxes in Adobe Reader 9 (9.3.3 & 9.4.0). Anyone that has Adobe Acrobat or Bluebeam PDF Revu can see the Chinese in the Callout boxes fine.
Any Chinese text that appears in the document is fine in Reader. The problem appears to be restricted to the Callout boxes.
I also tried installing the Reader 9 Font Packs but it didn't help. I didn't think it would because other aspects of the PDF are OK.
Suggestions?

Reflecting on the conversation I realize that she was probably not skilled with the Acrobat family of products but just reading scripted possible solutions from a knowledge base.
