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.

The following example demonstrates IsSeparator.

using System;

public class IsSeparatorSample {
	public static void Main() {
		string str = "twain1 twain2";

		Console.WriteLine(Char.IsSeparator('a'));		// Output: "False"
		Console.WriteLine(Char.IsSeparator(str, 6));	// Output: "True"
	}
