As far as I know, every single font that comes with Windows, with the possible exception of a couple of "wingdings / webdings" type fonts, support the ° character.
It is likely that you are pasting the ° character into your skin .ini file without first changing the encoding of the .ini file to UTF-16 Little Endian. The issue is that if you are using a default encoding of ANSI, when you paste in an Extended ASCII character, one that is above 128 in the ASCII/Extended ASCII character set, then the file will be saved as UTF-8 w/o BOM, and that isn't going to work right with Rainmeter. That ° character, ASCII 248, will be replaced by some weird symbol.
Inside baseball: ANSI and UTF-8 are exactly the same thing as long as the file contains only characters from the ASCII set from 0-128 in decimal. When characters from 129-255 are used, then it will be seen as UTF-8 w/o BOM. UTF-8 is fine for the web, and is the standard there. Windows, and Rainmeter, hate it.
I strongly suggest that ALL Rainmeter skin .ini files be encoded as UTF-16 LIttle Endian. This will allow you to use any of the characters from the ASCII / Extended ASCII set, as well as any Unicode characters. Unicode of course has the additional imitation that the font you are using in the skin must support the character(s), but most decent fonts support a wide range of Unicode characters. This is one of those situations where doing it this way can never hurt, but not doing it can lead to confusion and problems. Just get in the habit.
Note that the new "Create new skin" functionality in Rainmeter's Manage dialog will always create new .ini files as UTF-16 Little Endian.

The encoding you want in different text editors:
- Unicode (Windows Notepad.exe)
- UCS-2 LE BOM (Notepad++)
- UTF-16 LE (Sublime Text)

Note that the characters in the Extended ASCII set, those from 129-255, may be different depending on your Language / Locale in Windows, to support language characters other than standard Latin / English. Having said that, in my experience 176 is always the degree symbol °, as that is something pretty much every language uses.
