Redmine

We are seeing an issue in Redmine where pasting 'smart' quotes from Microsoft Word 2010 or Microsoft Outlook 2010 into a redmine issue then results in unexpected character output if we export to pdf or to csv. Basically the quote is changed to a string of 'garbage' characters.
eg:

We’re testing apostrophes (Word)
We're testing apostrophes (eXcel)
We’re testing apostrophes (Outlook)
we're testing apostrophes (Notepad)

This looks/feels like a codepage issue but we can't pin it down. Has anyone seen a similar issue that might be able to give uss ome ideas of what the exact problem is here?
