Is there a command option to suppress the generation of the secondary svg file?

I am using plantuml-mode emacs plugin to generate svg files in emacs and I noticed that an additional svg image is created which cause Firefox and Chrome to generate an error

This can be seen after line 29 in the pastebin at

I have used the stable sourceforge version  of 2020.01.12 and the latest beta at 2020.02.02 from and they all add the additonal svg.

I have asked a question about it at, but realize that it must be an option that needs to be suppressed or requires a separate build.

Are there some options to control it?

Is there a list of the command line options plantuml accepts?

See my answer in your previous question. it should be the ob-plantuml issue, save your plantuml code block into test.puml and use the command line you will get the expected result:

java -jar plantuml.jar -charset utf-8 -tsvg test.puml

ob-plantuml checks if the content starts with `@start` and if not it adds `@startuml` `@enduml` around the content.

If `@startuml` is not at the beginning of the first line it is not found and added again.

im running into the same problem, but i can't fix it. 
Is there any way to disable the ob-plantuml auto mode?
If i decode URI: 

Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response

This comes out. In PNG no Problem but in SVG it generates a second XML TAG.
Even if i don't encode @startuml und @enduml it decodes with two start and end tags.
Encoded: SyfFqhLppCbCJhLIy4ZDoSa70000 Bob->Alice: Hello (without start und end) 

Thanks for any reply :)

Well, it looks like an issue on ob-plantuml side. This forum is somehow dedicated to the core PlantUML library.

You should probably report this issue to

Sorry about that !
