I suppose it's about Unicode General-Category
IsDigits tests for Nd
Is Numeric tests for Nd+Nl+No

for example chinese numbersigns are numeric but not digits.

Char.IsNumber returns true for a much larger set of characters.
Char.IsDigit includes only characters with the UnicodeCategory
DecimalDigitNumber, while Char.INumber also incudes the LetterNumber and
OtherNumber categories.
