    Numerals are characters that can be strung together in a positional
    system to form arbitrary combinations, which are themselves numbers.
    Not all of the characters in the block you mentioned are like that.

    Contrast U+0BE6 through U+0BEF, TAMIL DIGIT ZERO through NINE, with
    U+0BF0 through U+0BF2, TAMIL NUMBER TEN, ONE HUNDRED, ONE THOUSAND.
    Among other things, note the difference in General Category: "Nd" for
    the "digits," "No" for the "numbers."
