Weird Character output Field Collection data with Views Data Export (CSV)
You have UTF-8 characters in your data. The Â character in your case is a UTF-8 non-breaking space, but it's being rendered with the wrong encoding.

You might be looking at the output in something that can't render UTF-8 correctly (some old, dumb text editor), or if you're using something that does understand UTF-8, perhaps the wrong encoding (i.e. iso-8859-1) was chosen when you opened the csv.
