Windows font that clearly disambiguates the number ZERO from letter O

Question

Our intranet web pages need to clearly disambiguate between the letter O and the number ZERO. Is there a screen+printer font that is installed on WindowsXP and Vista that does this either putting a dot inside zero or a slash through it?

If there isn't such a font on the machines themselves, is there a way to embed the font in the page, or some other way for the web page to substitute a glyph for the zero glyph in one of the standard fonts, like Arial?

Thanks

Answer 1

Consolas, which comes with Vista and Windows 7 IIRC, has a slashed zero. It should also come bundled with later versions of MS Office.

You might find one of these other programming fonts useful too.
