isWhitespace
Determines whether a character is whitespace.
A character is considered whitespace if either its Unicode category
is one of CharCategory.SPACE_SEPARATOR, CharCategory.LINE_SEPARATOR, CharCategory.PARAGRAPH_SEPARATOR,
or it is a CharCategory.CONTROL character in range U+0009..U+000D or U+001C..U+001F.
Returns true if the character is whitespace.
