Update degree symbol to utf-8 encoding in comments

Almost all of the places where we have the degree symbol '°', it's
    encoded as 0xc2 0xb0 (utf-8 encoding).  There are a few places where it
    is encoded as just a high ascii byte: 0xb0.  Editors that support the
    high ascii 0xb0 seem to support the utf-8 0xc2 0xb0 encoding as well,
    but the opposite does not seem to be true.

Change the high-ascii degree symbols to utf-8 encoding.
