The mode line indicates that Emacs is using the Latin-1 character encoding. According to Latin-1 encoding tables, the degree symbol is encoded as decimal 176, so that's what I used in my code. But when the character printed, it wasn't the degree symbol; it was a "shaded box" looking thing. Then I looked at an ASCII table here (http:// www.asciitable.com/), and it says that 176 is indeed the shaded box that was printed in my program, and the degree character was decimal 248. So I used 248 in my code, and I got the degree symbol I wanted. But all this leaves me with the question that if Emacs was supposedly encoding the file in Latin-1, why doesn't the code for the degree symbol match up with the Latin-1 table? Why does it instead match up with some non-standard "extended" ASCII that I just happened to come across. Can anyone shed light on this? Thanks
