Remarks
Determines if the specified code point is a white space character. A code point is considered to be an whitespace character if and only if it satisfies one of the following criteria: <ul> <li> It is a Unicode Separator character (categories "Z" = "Zs" or "Zl" or "Zp"), but is not also a non-breaking space (\u00A0 or \u2007 or \u202F). <li> It is \u0009, HORIZONTAL TABULATION. <li> It is \u000A, LINE FEED. <li> It is \u000B, VERTICAL TABULATION. <li> It is \u000C, FORM FEED. <li> It is \u000D, CARRIAGE RETURN. <li> It is \u001C, FILE SEPARATOR. <li> It is \u001D, GROUP SEPARATOR. <li> It is \u001E, RECORD SEPARATOR. <li> It is \u001F, UNIT SEPARATOR. </ul>
This API tries to sync with the semantics of Java's java.lang.Character.isWhitespace(), but it may not return the exact same results because of the Unicode version difference.
Note: Unicode 4.0.1 changed U+200B ZERO WIDTH SPACE from a Space Separator (Zs) to a Format Control (Cf). Since then, isWhitespace(0x200b) returns false. See http://www.unicode.org/versions/Unicode4.0.1/
