Well, it's not that hard to write a perl one-liner and see if any of them matches \d, is it? It takes far less keystrokes than your question.

Having said that, as far as I can determine, 一 (CJK UNIFIED IDEOGRAPH-4E00) and 十 (CJK UNIFIED IDEOGRAPH-5341) are classified as a letter (\p{Lo}), with numerical values 1 and 10.

As I said before, to be considered a digit, you'll have to be a number between 0 and 9 (inclusive), and not part of a greater set. I do not believe 10 to be between 0 and 9.
