Sidebar Words.. Error?

Hey all. Ive got a blog at https://www.one.gavis.net/

The problem is, in Firefox, everything is fine. But when I view my blog in Internet Explorer, the sidebar’s words turn out in webdings or some other.. Weird language. Can anyone tell me whats going on?　Ｉ’ve switched many templates and it’s still having that problem. Even the default template.. I’m using the newest wordpress version btw. Thanks alog
