[OS X TeX] Invalid character in TS source

I sometimes open a selection in TexWrangler to find the invisible character. Sometimes, when I have a better knowledge of where it is, I step the insertion point through the text to see where the key stroke doesn't move the point. It would be great to be able to see it at a glance directly by turning on the TeXShop function of showing invisible characters.

By the way: thanks again, Dick, for the new Experiment feature, and for your continued work on that great app.

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.
