Thanks for your reply. Your reference to a "well-designed" font I assume
means a "fixed pitch" font such as Courier where a space occupies the same
horizontal distance as a 1. However, I'm looking for a solution that works
for a proportional font.
No, I mean both "fixed pitch" and proportional fonts. Try this with for
example Arial or Times New Roman, they work fine. As Suzanne Barnhill points
out: "In most proportional fonts, the numerals are, in effect, monospaced."
