' and Internet Explorer
It's old news, I know, but it's also useful to have a link to the complete ISO Latin-1 Character Set for Internet Explorer 4.0 and later to avoid seeing an ugly ' instead of the intended apostrophe.
For whoever does not know what I'm talking about, Internet Explorer does not support the ' entity added to the XHTML 1.0 specifications (since ' is an XML entity), which means that insted of showing an apostrophe it shows just '
Use ' whenever you need an apostrophe and everything will be all right.
