You need a good Unicode font. For Windows, the typical examples are Arial Unicode MS and Lucida Sans Unicode. At least the first one is included in recent versions (2003+) of Microsoft Word, for instance. Free Unicode fonts include the DejaVu font family. To examine a font, use the charmap.exe utility (Win+R, write charmap, Return; or, if you use Windows Vista/7: Win, write charmap, Return). You have to select "Advanced view" and Group By "Unicode interval". Then you can select "Mathematical Operators".

Thenk you for answer. I posted my comment like separate "answer" – rodnower Mar 20 '10 at 14:25

Not all fonts support all characters. You probably need to find a font that has glyphs for these characters and select it manually.
