We debated this point early in Unicode's history, and decided not to encode
a decimal point character. It was felt that it would be too easily confused
in practice with the period or comma (depending on the viewed locale), and
that software would always have to deal with legacy data and mis-typed
characters in any event.

By the same reasoning, we ruled out other possible generic punctuation marks
that would have very different representations in different countries:
abbreviation mark, thousands-separator, double and single generic quotation
marks, etc.

If you want to represent the raised dot used with older style numbers, I
think the hyphenation point is the right character (but I don't remember
