I was trying to remove the -- WordPress and WordPress >

I was trying to remove the — WordPress and WordPress › from the titles of Admin and Error pages but it does not seem to work :disappointed:

Here is what I have it set to do:
Look for: "— WordPress"
Change: "— APNetwork"

Look for: "WordPress ›"
Change: "APNetwork ›"

I'm assuming it is a problem with this '—' character.
