Once you 'Submit' your post, you can edit it to remove the junk as I've done to your quote above. TBN didn't used to add the junk, but I've just taken to writing out "degrees" rather than take the extra editing step.
BTW: If you hold down the ALT key and type "0186" or "0176" with the keypad, you can get degree symbols also. I prefer the looks of Alt+0186. You have to use the KEYPAD only. Using the numbers on the top row of the keyboard will not work. Here are examples Alt+0186 is コ and Alt+0176 is ー. The difference is very slight, but the 0186 is larger.
