What symbols can be put in group names?

[FlyingGrass]

I tried to add symbols to my group's name, but most of the symbols were missing, there was just the : in the username on the other's screen while I saw all the added symbols. There was 3 different symbols, :, _ and \. What are all the symbols supported in group names?

Also, when I switched maps after adding the symbols, my character's group name wasn't showing up in the character info panel on my screen.

@#_&-+()/*"':;!? are some of what I imagine to be used in a Group title. Others may include ,~`|^={}\%[].

Thank you!
That list includes all the symbols my group's name has, so do I need to restart the game to fix the group's name so all the symbols appear? I'm worried the group could go poof if I relogged, is it possible for renaming a group to somehow disband it? The group is small, so I can re-invite everyone if it accidentally disbands.

No disbandment of the group should occur whatsoever and game restart shouldn't be necessary. However, if you feel that a restart of your game is required to ensure that the name change has been saved, feel free to do so.

Bit of an unnecessary side note, but it's been noticed before that typing in the \ symbol (or it could be the /, it's one of the two) and exiting out of the bio/group name/group bio that it was typed in causes it and occasionally the characters following to disappear. Bit of an unreliable little character, yeah? So no need to worry over that one.
