Can we use this rule for name changes?

Question

No Emoji.

When you use your phone for it, people on windows get blank boxes.

Make your name legible. What the hell is this?: ♠₪₹Ͼαﬨϕ₰₮ﮞӆд₹₪♠

We could just in general keep it to one or two symbols per name, this actually looks good: ƒιzz

My stance:

1) Emoji is bad. I agree.
2) I agree. Maximum 4 symbols I'd say, and I'd count symbols as anything not on a QWERTY keyboard, excluding dots, and letters with accents.

I think a name's legibility doesn't really matter - it's that person's user name, in the end. They could go by a nickname, or at least have one legible character in their name to go by. :P
But if the rule does end up applying then the name just needs to be reasonably legible. Can of Tuna's name is rather hard to read, I agree, but sometimes some symbol-filled names are not as hard to read.
