I'm having an odd problem with some of my pages concerning apostrophes. The apostrophes in words such as I've, wouldn't, and other contractions show up when opened with the browser (firefox) but not when opened with the editor (notepad++) In the editor they're missing and when I put them in with the editor I get two apostrophes when viewed with the browser. And when viewed with the browser it looks like the apostrophes are two different fonts. Something like this. I''ve wasn''t with the second apostrophe looking like a different font and not visible in in the editor (notepad++).
Does anyone know what's going on and how to fix it?
