>A 'space character' is the single character \x20. A 'whitespace
>character' is any character in a some set of non-printing (white)
>characters. I guess it is a subtle distinction but it's common usage,

>(Not to be confused with Whitespace the programming language, in which
>all *non* white space characters are ignored:
