Whitespace Characters
Unicode provides a list of characters it deems whitespace characters for interoperability support. Software Implementations and other standards may use the term to denote a slightly different set of characters. For example, Java does not consider U+00A0 no-break space or U+0085 (NEXT LINE) to be whitespace, even though Unicode does. Whitespace characters are characters typically designated for programming environments. Often they have no syntactic meaning in such programming environments and are ignored by the machine interpreters. Unicode designates the legacy control characters U+0009 through U+000D and U+0085 as whitespace characters, as well as all characters whose General Category property value is Separator. There are 26 total whitespace characters as of Unicode 6.0.0.
