ASCII isn't really enough for (British) English. In handwritten English the following characters are very common: £ ‘ ’ “ ” · –/—. (You see that interpunct? That's the correct way to do a decimal point. Very common in handwriting; very rare in typing; often replaced with a full stop even in good typography.) Then there are some frequently used foreign words: façade, outré, Noël. I'll mention these, though they're rather old-fashioned and I would guess nearly everyone would use the ASCII equivalent even in handwriting: naïve, encyclopædia, œuvre. I could also mention the grave accent used in some poetry: learnèd. Dutch, like English, is almost ASCII, though there are things like "één".
