TouchUp Text Tool Issue

I am experiecning a strange issue on a PDF that was created from Microsoft Word 2007. It is a two page document but I am only able to use the TouchUp Text Tool on page one. I do not get the "I-Bar" cursor on page two to edit the text. The portion that I want to edit has a strange character in it, if that helps: It is obviously supposed to say "Yes" but, for some reason, it does not. I am using Acrobat version 9.5.5 on Windows 7 SP1 x64. Any help with this is greatly appreciated. Thank you.
