When a Word document is loaded that contains traditional Chinese characters (PMingLiU font) these characters are not visible when saving the document as pdf or xps. They are converted to the missing placeholder square icon. All other formats are fine.
Viewing the word document on the same machine as the documents are generated so the fonts are installed.
Application is a web app running on IIS7. Save code below:
m_Doc.Save(filePath, SaveFormat.Pdf)
