Hi, Out of the box, ob-ditaa does not work with non-ascii characters.
I looked into the problem in order to answer a user request on StackOverflow (yes, there are org-mode questions posted there instead of here!). http://stackoverflow.com/questions/5758498/problem-with-ditaa-and-foreign-characters-in-org-mode In order for ditaa to accept UTF-8 characters in the input file, it must be called with the corresponding property setting: java -Dfile.encoding=UTF-8 -jar path/to/ditaa.jar ... Attached is a dirty patch for hard-coding this property setting. I don't know what the proper way of setting this property should be: - somehow setting it system-wide (any Java guru out there?). - or adding a customization to ob-ditaa.el for this property - or adding magic to ob-ditaa so that the same encoding of the buffer gets set to this Java property I can help with the implementation if given some feedback on the above options. Regards, .j.
