Special characters not showing

Question

Hello, I am having a strange problem with showing special characters in the browser when I upload the site. (its fine when I view it on localserver)
For example on my website: http://www.reese-test2.co.uk/
if you do a search for example: 3GLG534WW - instead of seeing the degree symbol there is a �
it should read 35° beam angle not  35� beam angle
I know i could go through all 500 products and change the beam angle character on my SQL database to:   35°
But surely there is an easier way? This being a lighting website for my work I have other special characters that will also show up weird, so would be good if there was an easy fix to this. I am using WAMP, and DW CS6.
Is there a line of code I can add to my results.php page that will force the characters to show properly?
thanks
Sara

Hi Just thought I would update this post. My server provider said they cannot change the character set due to how they were set up, so had to do a find/replace in PHPmyAdmin - (SQL tab) instead.
Ken thanks for your idea. This didnt initially work for me, so googled it and had to make a couple of changes to the code, but this then worked. "Replace" needs to be in caps and the brackets removed.
Original:
update [table_name] set [field_name] = replace([field_name],'[° ]','[°]');
Correct:
UPDATE productsearch SET description = REPLACE (  description,  ‘°’,  ‘°’);
thanks for your help Ken Binney
