We have seen a few issues of people emailing tasks to their Get It Done account and some of the extended characters do not come through correctly. We found a work-around which should fix the issue. To fix the issue, make sure your email client always sends messages using utf-8 encoding. Here are the instructions for Outlook:
Click the orange "File" tab in the top left corner of the Outlook 2010 window and click "Options" on the pull-down menu. A new window titled "Outlook Options" appears.
Click the "Advanced" heading on the left side of the window and then scroll to the "International Options" heading near the bottom.
Place a check in the box labeled "Automatically select encoding for outgoing messages" and click "Unicode (UTF-8)" on the drop-down menu.
Place a check in the box labeled "Allow UTF-8 support for the mailto: protocol."
