How to make msn letters?

How do you make small letters in your MSN nickname like these > ᴬᴰᴼᴿᴱ <?

• i see people with these nicknames that have really small text that says some cute stuff, where do they get them from ? please answer asap!!

• Answer:

  OK some people find that when they do this the screen needs to be a full screen but i can do it without. Basically you hold Alt which is on the left side of the keyboard and then type any number combination you want using the number pad (the right side of the keyboard) e.g ß = hold alt and press 225
