In all of the Magic the Gathering: Duals of the Planeswalker games so far, you can add mana symbols (and other symbols?) to your name using special character sequences.
What are all the character sequences?

According to this post on steam, this is what you have to use:
Anything enclosed in {} in your Steam Profile name will be interpreted by the game as a symbol. The mana symbols are BWRUG (black, white, red, blue and green respectively). X, 0-9, and k-p (lower-case) are colorless mana costs. Various other letters and punctuation produce other symbols, such as Xbox or PS buttons, arrows, etc.

{#}, where#is some letter or number (possibly more than one??). But there doesn't seem to be a list of them all online anywhere. – BlueRaja - Danny Pflughoeft Aug 1 '13 at 16:53
