Font to show difference between 0 and O

[Bill Vlahos]

The Monaco font on Macs clearly shows the differences between a zero  
and the letter "O" and the number one and lower case "L", etc.

What would the equivalent font on Windows and/or Linux be? It doesn't  
have to be a monospaced font; just one that shows the characters  
unequivalently. Preferably the same font could be used for all  
platforms.
