    getNumericValue() will convert characters that actually represent numbers (like the “normal” digits 0-9, but also numerals in other scripts) to their numeric value. The Characters represented by Character.MAX_VALUEand Character.MIN_VALUE do not have such a numeric value; they are not numerals. And according to the API doc:

    If the character does not have a
    numeric value, then -1 is returned.
