I assume it's not just me: Why have some users added special characters to their usernames? The list includes:

(OK, me too... drm65 turned into drɱ65 δ)

  • And what letter is that: z7sg Ѫ

  • @GEdgar: If you use Firefox, the addon "Character Identifier" lets you highlight text and get Unicode data about the characters. Ѫ happens to be U+46A, CYRILLIC CAPITAL LETTER BIG YUS.

It's a chat thang. Various theories abound about how it started:

  • It's all Alain Pannetier Φ's fault
  • But since he added his Φ in direct imitation of the CHAOS team's Ψ, it's really all Joel's fault
  • We're just χάοτικ by nature
  • It's to celebrate EL&U's birthday

Note that there was argument about how the trend started all of 5 seconds after it started, so you will probably never get a definitive answer.

  • Also: I don't know if Bogdan really counts as an instance of this trend, since Lătăianu is how his name is actually spelled in proper Romanian orthography. Aug 12, 2011 at 14:01

    @JSBᾶngs, except his handle used to be spelled Lataianu, and now it's spelled Lătăianu. So he changed it to go along with this trend, same as the rest of us.

It's a new trend: To be cool, you need to have at least a greek letter in your username. Just don't use Ψ, if you are not part of the CHAOS project.

In the case of RegDwight, as he is moderator, the diamond () is used to show he is a moderator; it's not a character he added to his username.

  • What about you? And ª isn't a greek letter.

    I have never said to be cool. ;-) Plus, my username is in Esperanto; I should eventually use Esperanto characters, but those in kiamlaluno are the same used in the English alphabet.

    Shouldn't CHAOS be χ, or would that not be chaotic enough? Sep 10, 2011 at 18:43

    @Peter Shor The Ψ is more mystical, as it seems a candelabrum.
