How to escape a word in a query string?

Question

I have a URL that looks like this more or less:

www.xyz.com?parameter1=value&region=global

The problem is that some browsers are literally changing &reg into ® so the URL is breaking because it's turning into either

www.xyz.com?parameter1=value®ion=global or www.xyz.com?parameter1=value%AEion=global

Is there a way to escape out a value like that for URL web queries? Or is it best to just avoid certain character combinations?

(the manual fix is to swap the parameters around so it's ?reg instead of &reg but that's an annoying manual intervention every time...)
