Java BufferedWriter object with utf-8

by

No. FileWriter doesn’t let you specify the encoding, which is extremely annoying. It always uses the system default encoding. Just suck it up and use OutputStreamWriter wrapping a FileOutputStream. You can still wrap the OutputStreamWriter in a BufferedWriter of course:

BufferedWriter out = new BufferedWriter
    (new OutputStreamWriter(new FileOutputStream(path), StandardCharsets.UTF_8));

Or as of Java 8:

BufferedWriter out = Files.newBufferedWriter(Paths.of(path));

(Of course you could change your system default encoding to UTF-8, but that seems a bit of an extreme measure.)
