I find them the same way Gary does, though I usually use AlphaX rather than BBedit.  There they appear as little squares, so I can't tell you exactly what they are, but when I delete them TeX (or in my case, XeLaTeX) is happy enough to run again.   Not a big deal, but this combination has the potential to be a bit of a problem for newbies, I think.

Howdy,

The real question is why are these things being embedded in your file? Is the file UTF-8 encoded? If so they may be bytes for a multi-byte character code. If it's a UTF-8 with BOM than only the first two or three bytes might be messed up.

Good Luck,
