I have been talking about this problem since the early nineties.
Back then, I remember getting a letter from
Patrick Coyne, editor and designer of
CA, in response to a newsletter article where I wrote about this problem in the
ADAI newsletter. As a young designer, I was thrilled to get the letter. I still have it.
Here it is 2010 and the problem is still rampant.
Ever since desktop publishing replaced type houses, it seems even professional designers, sign shops, ad agencies and others are in violation.
What I am referring to? Typographically incorrect apostrophes.
How do you know when this type violation occurs? The apostrophe should look like a comma. It should not look like a foot mark (sort of like an exclamation mark without a dot).
This violation happens with quotation marks too. Some computer software doesn't compose type automatically with correct apostrophes and quotation marks. The person typing doesn't notice.
It shouldn't be a consumer's job to catch this mistake, but now you know, so be alert. I you buy a building sign, a menu, a billboard, an ad for your company or the like, be alert for this common mistake.
Don't even get me started on bad typography on web sites.
