I don't really care of the meaning of characters. I agree though in a group they mess up the name order and some people just use them to their name show up first.

most of the examples you gave are symbols, which are widely used, think first and last is Neptune. Used in astrology and astronomy. As for gang signs, the one in the news was just regular numbers and letters lol. Occult is basically anything not Christian so thats being quite discriminatory which is not what LL is about. This is just for display names anyway and people can have what they like.

Complete non-issue. This only serves to limit creativity for people's names.

This is not needed. The characters mentioned in the OP are only present in display names. As stated below only certain characters are allowed in usernames. If you don't like characters used in display name, then you can always switch to usernames. This is really a none issue.

i disagree with this. limiting others expresion for your own convenience is absurd

Absolutely AGAINST disallowing unicode characters. Who care if someone uses occult symbols? This has nothing to do with "finding" an avatar.

what's wrong with the occult? Anyway the symbols are unicode which are chosen by an international body that's in charge of creating then. The use of them to create elaborate and overly complicated names goes back to the early internet and ascii art and haxxor. Its just a unique way for people to write their names. If you want to just see legacy names for ease of identifying a player the viewer can show legacy names only on the name tag. Praise Lilith the Dark Mother

SL is rife with gang-related and occult merchandise, none of which appear to be against the SL community guidelines. And who is going to decide what is offensive and which characters are going to be banned? That's going to be a really long, hard and tedious debate, more like opening a can of worms.

Case in point: ψ (psi) is an simple Greek letter. What if someone want to spell out their name in their native Greek alphabet? It's also the mathematical symbol for the wave funtion in quantum physics. Without physical wave funtions, we would have no quantum electrrodynamics, no microcomputers and no Second Life.

Display names are not things that actually identify an avatar. Account names, which are, are already restricted to /[a-z0-9]{1,31}/

I see this post is tracked. As much as I'm tempted to think of the wording of the OP as funny, it would actually just be tragic for LL to roll back the point of display names and limit which perfectly valid unicode script characters are usable because of input like this.

Where would it end? One of the characters you show is a valid letter in Greek for example, another looks familiar too, maybe from Thai.
