I used a HTC Desire with Android 2.3.3 and also a Sony Tablet with Android 4.0.3 with the default PDF viewers.
Thanks for sharing the information. Can you please share the name of default PDF viewer which you are using. Is it Adobe Reader ? as I came to know that since the release of Android 2.1.+, Adobe Reader is freely included in Android. However I have used Adobe Reader X, version 10.2.1 and Build 60548 to view the PDF file.
Please note that I also tried viewing the file in Office Suite and all the contents were properly being displayed. We are sorry for your inconvenience.
