Go on twitter to the tweet box in the upper left. Write @, then other characters. Some cause special actions (like r -> reply), others simply do nothing. Some work as intended. These are the characters that I can use in other user names: acdegiknpqsvwxyz Reproducible: Always
It looks like you can get all characters if you just hold down the key of one of the non-working characters. After a while many of those characters will show up and you can just delete all but one. If you press e.g. "u" once a second you can only write "@u", but not "@uu", but holding down u will eventually make more "@uuuuuuuuuuuu..." show up.
