maybe this: https://www.tutorialspoint.com/java/io/inputstreamreader_getencoding.htm edit: it seems like you just get the encoding of the stream with this. Getting the encoding of a file is much more complicated. You might actually have to use libraries(e.g. guessEncoding) for this task... https://stackoverflow.com/questions/499010/java-how-to-determine-the-correct-charset-encoding-of-a-stream
