In typing dialogue in a story, all of a sudden, the quote marks changed from
regular ones, "like this," to: €žThats a remote possibility.€œ

Note that the "open quote mark" is down and the "close quote mark" goes the
other way than it should. I'm in Courier, if that means anything.

I cannot find out where the problem comes from. In looking at the Character
Map, I have found these marks. The first one is U+201E: Double Low-9
Quotation Mark.

I finally deleted the whole section and retyped it and had no problem. How
do I stop this from happening again? I certainly didn't hit the Unicode key
combination by mistake.

I'd appreciate any help you can give me.

Thanks,
Ann
