The Unicode standard recognizes three subcategories of separators:
Space separators (the UnicodeCategory::SpaceSeparator category), which includes characters such as \u0020.
Line separators (the UnicodeCategory::LineSeparator category), which includes \u2028.
Paragraph separators (the UnicodeCategory::ParagraphSeparator category), which includes \u2029.

The Unicode standard classifies the characters \u000A (LF), \u000C (FF), and \u000D (CR) as control characters (members of the UnicodeCategory::Control category), not as separator characters. |
