New line in string issue

Question

So I have an issue, where I need to use a string that contains a \n, but that does not translate into a newline in unity 5 for some reason.

So below is where I want to set this in the inspector:

alt text

Then I write this to the Canvas in the below function:

     public void addLogMessage(string Messagetoadd) 
     {
         logMessages.Add(Messagetoadd);
         
         LogPanelText.text = Messagetoadd;
         
         LogPanelText.text += "\n\nPress L to show / hide last log message.";
         
         showLogMessage();
     }

But that seems to not translate into a new line:

alt text

Can anyone help, what am I doing wrong here?

I have tried that and unfortunately that does not work either. In unity 4.6 you would see in the inspector that there was a carriage return, but now it just seems to add a space.

Well then, I've designed a special method, which will manage this new line character like so:

 private string $$anonymous$$anageText(string InText)
     {
         int CIndex = InText.IndexOf("\\n"); // Gets the Index of yur "\n" Char
         InText = InText.Remove(CIndex, 2); // Removes "\n from original String"
         InText = InText.Insert(CIndex, "\n"); // Adds the actual New Line symbol
         return InText;
     }

Try to play with Input String and you will see the results :)

it's like turning the food two times around your head and then put it in your mouth. why not just using InText.Replace("\\n","\n"); return InText; ???

So for anyone else that might need to do this, it was achieved with the following funtion:

 private string newLineReplace(string InText)
     {
         bool newLinesRemaining = true;
         
         while(newLinesRemaining)
         {
             int CIndex = InText.IndexOf("\\n"); // Gets the Index of "\n" 
             
             
             if(CIndex == -1)
             {
                 newLinesRemaining = false;
             }
             else
             {
                 InText = InText.Remove(CIndex, 2); // Removes "\n from original String"
                 InText = InText.Insert(CIndex, "\n"); // Adds the actual New Line symbol
             }
         }
         
         return InText;
     }

you can then say something like this to show it

 LogPanelText.text = newLineReplace(Messagetoadd);

Hello!

New Line: "\r\n" instead of "\n" worked for me. I got this from this one: https://answers.unity.com/questions/16865/making-newline-n-in-inspector.html
