}

This script will show you how your name looks with the formatting too.

code:

---

function OnEvent_MyNameChange(NewName){
  MsgPlus.DisplayToastContact("Messenger Plus! Live", NewName, "Changed Name");
}

---

This scipt will show you straight away after changing your name how it looks to you contacts including the formatting.

I hope these help you.

EDIT: RaceProUK is correct, the only way we can change this is with a scipt.  The advantage with using a scipt aswell is that it is easily adaptable to however you want it (eg formatted, unformatted, with different text, etc.), if microsoft were to do this for you then you woud have to put up with it how they wish for it to be for you.
