“Why does it matter which form of encoding we choose? What happens if we choose the ‘wrong’ one? The choice of character encoding affects the range of literal characters we can use in a web page. Regular Latin letters are rarely a problem, but some languages need more letters than others, and some languages need various diacritical marks above or below the letters. Then, of course, some languages don’t use Latin letters at all. If we want proper — as in typographically correct — punctuation and special symbols, the choice of encoding also becomes more critical.”
