Character encoding question

Hi, I'm using Tomcat 6.0.26. I'm noticing that when our JSPs pages are served, we frequently have ?s where apostrophes should be. We think this is because the database-driven content contains the Microsoft style apostrophe. My question is, if I adjust the character encoding on Tomcat, will
