Well, I'm afraid my mind-reading skills aren't good enough to answer that,
but my mail client doesn't show them (TB under Windows).

However, it didn't take long to find out that they are UTF-8 C2 A0
sequences, which is the code for a non-breaking white space.

The mime header does have "Content-Type: text/plain; charset="UTF-8"", so
it looks like your email client may be to blame.
