Because of POSIX isdigit():

digit 
Define the characters to be classified as numeric digits. 
In the POSIX locale, only:

0 1 2 3 4 5 6 7 8 9


shall be included.

In a locale definition file, only the digits <zero>, <one>, <two>, 
<three>, <four>, <five>, <six>, <seven>, <eight>, and <nine> shall be 
specified, and in contiguous ascending sequence by numerical value. The 
digits <zero> to <nine> of the portable character set are automatically 
included in this class.
