One of the first things to do when you have a screenful of the
wrong characters is to whip out an ASCII chart, and look at the
binary codes for the characters you've got vs. the ones you
expected. Very often the problem is a single-bit change, which
narrows down the source of the problem. For instance, the
difference between upper- and lower-case ASCII characters is a
single bit.
Cheers,
Bill.
