Request: support escape character in state diagram

Some characters, like . or #, can not be escaped in state diagram, but it will be helpful if we want name the state name of self.newstate or some like this.

I’m super excited that Mermaid diagrams are now supported by Github! And the first issue, I bumped into, is lack of support for :: in the class name (I need a C++ class diagram and it’s very natural to have namespaces for C++ classes). I’m glad that a workaround with escaping names by enclosing them in backticks is available. Though, would be good to document it in the ClassDiagram docs and possibly enable it without backticks.

Here’s how it works now.

Source:

classDiagram
    class `a::A`
    class `b::B`

    `a::A` --|> `b::B`

Rendered:

classDiagram
    class `a::A`
    class `b::B`

    `a::A` --|> `b::B`

I’m having the similar problem with classDiagram which doesn’t allow me to use C++ namespaces class names

classDiagram
    class a::A
    class b::B

    a::A --|> b::B
