The interesting difference between ASCII and Unicode is that the first had only one group of digits defined (30h to 39h), and the latter defines 42 decimal digit groups (I think it actually defines more, but nvm). A common programming language operation is to convert a sequence of digit-characters (yes, a number) to a machine-understandable integer. Does any default in-language string-to-integer support Unicode digits? Does any is-digit function return true on Unicode digits? Well, I did some checking and created a table (programming language/version/library vs digit group) that addresses these questions.
