We have a small in-house application which generates a string consisting of upper and lowercase letters, and the numbers 0-9. We've tried using various fonts to output this string, but users frequently get confused between certain combinations like:

• Lowercase letter 'o' and uppercase letter 'O'
• Uppercase letter 'O' and number '0'
• Lowercase letter 'l' and number '1'
• Uppercase letter 'S' and number '5'

and so on.

Can anyone recommend a font that might be suitable?
