String.Trim() removes more than need?

Question

I found a ticket in our issue tracker that one of customers report a bug that one texts is incomplete! We have a text conversion program from one legacy system(IBM AS400) to a modern one. I tracked it and found an unknown behavior on my code!!

Yes, Trim() removes char160 from beginning! What happened that Trim() works more than need? Note: both pictures are captured in same test state.

Answer 1

160 is a NBSP (Non-breaking space) and according to the documentation, Trim will remove all the whitespace. 160 is classified in Unicode as whitespace.

You might want to call Trim(' ') instead.
