Yes. The symbol is a small open square. It happens with "J" and the section sign (double "s") and other standard word processing items. Vrery frustrating. I've checked the font and its Times Roman. I switched to another font--with the same results. Does the God of words hate me?
I followed your suggestion and the font I had specified came up--but the different key strokes I type produce the same character. Al I get is a kind of place holder.
I'll try. It occurs through out the 13 page (sorry--it's a newsletter)

Thanks. I and a colleague have been deviled with this.
