# How to convert {curly brackets} to tikz?

When I convert this

```@startuml
A -> B: {curly}
@enduml```

to tikz, I get the following (shortened) output:

```...
\node at (26.6pt,52pt)[below right,color=black]{{curly}};
...```

The problem is, that LaTeX ignores the brackets around {curly} when generating the PDF. One would have to escape those like this. \{curly\}.

Can this escaping be achieved with plantuml automatically, or is this a bug?
