in YA how do get to make symbols in your name under the pic of your avatar?

Click the "start" button on the lower lefthand corner of your screen. Click "run", enter "charmap", it will show all your installed fonts and the available characters and wingdings for each font. Try "arial", click on the character you want (it even contains musical notes and little hearts). You may click on a specific character to enlarge it slightly and by "copy & paste" you can insert it in any text you want to. On the bottom of the charmap window it will also let you know which keystroke to use for writing that character.
