Because the character "→" has a Unicode code point \u2192.

String s = "this is → my arrow";
if (s.contains("→")) {
  System.out.println("Contains arrow!");
} else {
  System.out.println("No arrows in my string :(");
}

As an alternative you may write the character in hex notation:

String s = "this is → my arrow";
if (s.contains("\u2192")) {
  System.out.println("Contains arrow!");
} else {
  System.out.println("No arrows in my string :(");
}
