Problem solved:
In 2.9.2 under “New Blog Defaults”, the field “Encoding for pages and feeds” was blank and should have been UTF-8. When I updated this field on all blogs, the problem went away.
In 3.2.1 you can edit this value on a blog by blog basis on the reading settings page: /wp-admin/options-reading.php. I’m not sure what the default value for new blogs in 3.2.1 is, or if there is somewhere to change the default, but I’m guessing it is UTF-8
