Okay, here is the Unicode version of the nick he uses: nick.txt (you might have to right click - save target as)
This isn't Messenger Plus! related though, I disabled Plus! completely and it would still shrink the nickname.
It doesn't seem to be one of the Chinese characters but a combination of several characters which does this.. I'll take a closer look later.
