Re: 2.9.0 ListBox getItemText(i) trims result [possible bug]

Mon, 28 Dec 2020 04:21:08 -0800 

And workaround is to encode all string put into/extracted from list with 
function:

private String encodeString(String s) {
  StringBuilder sb = new StringBuilder(s.trim().replaceAll(" +", " "));
  return sb.toString();
}

Maybe this will help someone
