If the user has a code FString that used "\n", that's interpreted as a line break and is removed. This can cause confusion for users attempting to get the length of the value since it will not match what they expect.

The specific case a user encountered was with a Google RSA key that had this in the string.

Steps to Reproduce

With Attached Project:

  1. Download and extract the attached project.
  2. Build and open the project in editor.
  3. Open NewBlueprint.


  1. Create a new code project.
  2. Create a new Actor code class.
  3. Add the following to the class header:
  • 	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Test)
    		FString TestString = "Test\nTest";
  1. Compile.
  2. Open the project in editor.
  3. Create a blueprint based on your class and open it.


Test String reads "Test Test" on two lines.


Test String reads "Test\nTest".
