Split String not working

I have a list of strings that I choose a random from and split using the '|' character, but when testing using the Debug.Log it returns the strings split by a white space ' '. I've tried replacing '|' with other characters but it only ever splits by white space ' '.



I'm transcribing some old code into Visual Code and the original line was as follows:

Code (CSharp):

1. string[] strPieces= thisStr.Split('|');

 

Switching it out to this works but seems like a turgid way of doing things..
