first code unit that is not a StrWhiteSpaceChar and all code units
following that code unit. (In other words, remove leading white
space.) If inputString does not contain any such code unit, let S

13. If S contains a code unit that is not a radix-R digit, let Z be
the substring of S consisting of all code units before the first
such code unit; otherwise, let Z be S.
