I'm looking for an easy and save solution to append text to a existing file in Java 8 using a specified Charset cs . The solution which I found here deals with the standard Charset which is a no-go in my situation. One way it to use the overloaded version of Files.write that accepts a Charset : import static java.nio.charset.StandardCharsets.UTF_8; import static java.nio.file.StandardOpenOption.APPEND; import static java.nio.file.StandardOpenOption.CREATE; List<String> lines = ...; Files.write(log, lines, UTF_8, APPEND, CREATE); Path path = Paths.get("..."); Charset charset = StandardCharsets
