jStarDictM-EE is the Encoding Enchanced version of jStarDictM.  It uses icuME to support any charset encodings.  If your dict's encoding is not supported by the jvm on your phone. You can try this. You need to don't the vnc files to your tf card. Please put the cnv file to dict\config\icu folder. Please get the cnv files from http://download.icu-project.org/files/icu4j/3.8/icu4j-charsets-3_8_d02.jar. This is needed if you are suing kdic dicts. For stardict format or dict.org format, they are all in utf-8, so you will not need to use the EE version.
