Japanese Support for Hotmail


Hello, this is probably a question for microsoft hotmail more so than this forum, but, in MS Hotmail, I've created an email using Kotoeri, and sent it out to several different addresses, including back to my own, and every japanese character returned becomes a question mark. Are there appropriate settings to fix this within the OS or the browser? I am using Safari v2.0 and OS X 10.4.1

appreciate any help, thanks
Another way could have been (sorry didn't check in during hte day) to have another browser.. e.g. Camino seems often just just get it what you are writing when it's a non-Latin charachter
