word processing glitch in iOS 6

Since downloading iOS6 I've had a problem with moving word processing files between the desktop iMac and the iPad in both Pages and all .txt files where the iPad apps delete all contractions/apostrophes. I've tried everything, including retyping the files and editing the aprotrophes back in at both ends, but nothing works; every time I open the files on the iPad, are deleted. Plus Elements files are showing up in the Dropbox folder "translated" into Asian characters. Both of these problems are new since upgrading the iOS.

Anybody having similar problems, and anybody have a solution? Thanks,

Brian
