Best way to encode Degree Celsius symbol into web page?

Question

How should I encode special characters into web pages? For instance I need this symbol ℃, which I used just by copying and pasting the character as I can see it now. This worked for the desktop browsers I checked with and also on iPad and iPhone but nothing is displayed on a Blackberry I used for testing. Is there a standard best practice for this?
