html - How to avoid displaying """ instead of quote marks? -

-

i have pc running windows 7. surfing web, see plenty of normal quotation marks (", ') around. occasionally, i'll see written out html entity this: ". see on well-designed, big budget websites designers should know they're doing, ign or cnn.

i'm curious why i'm seeing this, , if there's wrong browser or computer. real question this: there way prevent special characters appearing html entities when other people, older systems, view my website?

generally speaking, kind of code cause problem arise, , how can prevented?

probably web developer literally typed " , html editor made ". may check page source.
