I often use this opening, but I don't ever see anyone use it. I think it is great because of the openings for attack that you create without weakening your defenses.
I can only respond anecdotally, but my friends yell at me for being to passive when I pay the KIA, but I happen to agree that it's very good. People think that "less immediately aggressive" = passive, when it doesn't. It = safer.

You forgot O
And the Infinity sign.
By itself - Unclear
Over an equals sign - With Compensation
Also, using the standard FIDE notation, the Open and Close Parenthesis. Used for 2 things - draw offers and promotion:
32.Qb3(=) is Queen to be 3 and White offers a draw.
32...g1(Q) is Black pushes the pawn to g1 and promotes it to a Queen.
The forward slash is also missing, to represent "Draw". 1/2-1/2
Now if you read any articles or books, tack on ! and ?, or combinations of them, like !!, !?, ?!, and ??.
So not just the O is missing.
