I also encountered the same problem. But it seems not work perfectly by
letting "coding-system-for-write" be 'no-conversion. For example:
In my "test.org"

* test

#+BEGIN_SRC plantuml :file test.png
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
#+END_SRC

#+BEGIN_SRC plantuml :file test2.png
Alice2 -> Bob: Authentication Request
Bob --> Alice: Authentication Response
#+END_SRC

C-c C-c on the second src block does not create a right image.

So here is a new version of "ob-plantuml.el", which utilizes the io
redirection in shell directly.

Hope that it addresses the problem.
