          Are you talking about that string you posted? Because that's actually a unicode char sequence. If you have that as actual string data it may be a bit of a challenge to convert that back to unicode characters. This stackoverflow thread deals with the topic:

                But seemingly unappreciated by Vicky since there is absolutely no feedback from him/her.

                  Nope, and it seems they'll never return to give any feedback:

                    Yeah I noticed that too. You'd think that people would do at least the very minimal bit of effort to keep others in a frame of mind that they want to help you. But I'm silly like that.

                      Vicky's handle is very memorable. If Vicky had one of the fairly anonymous numeric handles then I would not remember to ignore him/her in the future.

                        I was just speaking hypothetically - I couldn't care one way or the other how much consideration someone shows myself, just as long as you don't start mouthing off. Its a free internets after all. But I do know that there are plenty of people who thrive on proper form, so its not too clever to go down the path of treating the forum like your personal answering service.
