Alternatives to ™

As you may know, ™ is supposed to be shown in the browser as the superscript TM (™), which stands for Trademark. Every browser does this correctly, except Netscape Navigator (even Mozilla aka Netscape 6 works fine). Is there something I can put instead of ™ that will work with all the major browsers, including Netscape Navigator?

™ works in IE at least...

Thanks. That did it.

or you could always use a mini graphic
