tools.appendString() writing overlapping charcters to Stream
I am using tools.appendString() to write validation error message to UI. This function is overlapping characters in the String (if String contains more than 1 word then first letter of 2nd word is overlapped on last letter of 1st word so on and so forth.).
This UI section was moved from Pega 5.5 to Pega 7.1 environment. This Section is working fine in Pega 5.5 but not in Pega 7.
