If you locale's codeset is UTF-8, then how come your terminal cannot display those quote characters? > Surely Emacs doesn't assume from the use of UTF8 that curly quotes are > displayable?

We are not interested in all of the Unicode characters, we are only interested in a few of them. Anyway, I think it works for everyone else, the question is why doesn't it work for you?
