Detecting Plagiarism Tip 2

A recent post by a colleague on an editing site made the point that

if text is copied and pasted into Word from e.g. Wikipedia, it can include non-breaking spaces (small raised circles instead of the usual dot seen with show/hide is turned on). These are practically impossible to type by mistake! Similarly, when text is copied and pasted from PDFs, odd line breaks/returns are imported—another give-away.

Thought I'd pass that along.
