Question title font renders 0 (number zero) much like o (lower-case letter)

Question

Currently, the font specification calls Georgia as the primary serif font for question titles. While undeniably an attractive font, its zero renders almost exactly the same as a lower case letter 'o'. This introduces a significant level of ambiguity:

While I think it extremely unlikely that there is a serif font that is readily available on most Unix user's machines that would have a slashed or dotted zero (the ideal), with only a small tweak to the CSS, it would be possible to improve the rendering of zeros for most users:

I'm reluctant to suggest a significant change as I think the overall look of the site is extremely professional - however, for a site for coders and geeks, having ambiguous zeros is rather unfortunate1.

With only a small change to the stylesheet, this can be improved. From:

#question-header .question-hyperlink {
     color: #155078;
     font-family: Georgia,"Times New Roman",Times,serif;
     font-size: 24px;
     ...
}

to:

#question-header .question-hyperlink {
     color: #155078;
     font-family: "Times New Roman",Times,serif;
     font-size: 28px;
     ...
}

Is this something that others are similarly exercised about? Could it be considered for a change?

Other example questions where this has an impact (mentioned in chat):

• What is signal 0 in a trap command?
• what is commit=0 for ext4? does mdadm not support it?
• Message while booting : "pci 0000:00:00.0: BAR 0: can't allocate mem resource [0xc0000000-0xbfffffff]"
• ext4 overrides my commit=100 mount option with commit=0

Answer 1

I too think this design could use addressing. As I mentioned in chat I have been bothered by this before and was going to bring it up on Meta and kept forgetting. Thanks for bringing it up.

I'm not attached to any particular choice so long as it's glyphs for key characters that matter to Unix related questions (like the number zero and letter o) are sufficiently distinct.

Answer 2

When writing by hand I always slash my zeroes and sevens.

Don't know which font does that (zeroes, 7 is already non-ambiguous) but I'd like to see it used.
