first of all: if the characters are displayed as “squares”, then it most probably means, they are ok! It means, you did not yet correctly modify the font settings of the Java VM, which starts your Developer, so the Developer can’t display the characters… If the characters were really broken, then you would see something like “?” or “#” for each char, depending on whether the data got broken during a wrong conversion inside the (Server) Java VM or during a wrong conversion during RFC communication.
Go to the “lib” directory inside the installation directory of the JDK used by your Developer and then rename the following files:
font.properties → font.properties_bak
font.properties.zh → font.properties
Another way to verify, that the data is still ok, is: add a savePipelineToFile as the very first step of your Flow and give the fileName the extension “.xml”. Afterwards open the file with InternetExplorer. IE should be able to display the Chinese characters correctly.
