New Workspace name restrictions



I’m really surprised noone has asked this yet, but when you create a new workspace, what are the character restrictions on the name? I tried to name it anything involving a capital D and it wouldn’t let me, but I’m still not sure what the complete naming rules are.


Strange it used to show a message Only lowercase letters, numbers, underscores (_) and dashes (-) are allowed
Not sure why it was removed but names must match the following regular expression
