Answer 1

I find iso-8859-1 very useful on a couple of sites where I have clients sending me text files that were created in Word or Publisher, that I can easily insert into the midst of PHP code and not worry about it - especially where quotes are concerned. These are local, U.S. companies, there is literally no other difference in the text on the pages, and I see no disadvantage in using that character set on those particular pages. All others are UTF-8.
