Add dot in architecture group name

[rvp-pro]

I want to display dots/periods in the group name. Example:

architecture-beta
    group api(cloud)[Application v1.0.0 High Level Design]
    service db(database)[Database] in api
    service disk1(disk)[Storage] in api
    service disk2(disk)[Storage] in api
    service server(server)[Server] in api
    db:L -- R:server
    disk1:T -- B:server
    disk2:T -- B:db

But I get this error:
Error: Parsing failed: unexpected character: ->[<- at offset: 38, skipped 1 characters. unexpected character: ->.<- at offset: 51, skipped 1 characters.

What is the right way to add dots? Or is it not supported yet?

huh - it does look like no 'escape'.

Even weirder is refusing ANY symbol, punctuation, or unicode in the label. I'd've expected the square brackets to collect most things.

Might be a better title - "architecture-beta label doesn't support punctuation etc"? Love betas 😁
