Non-English will be garbled

[lnkForKing]

When executing the command, the encoding has been hard-coded. Use 436 and when receiving the returned result, the string uses the system encoding (my default system encoding is UTF-8). If the result of using the command to execute the script contains non-English, it will return garbled characters.
I hope the author can optimize this point and can specify the encoding instead.

WinRmClient.java

`

public ShellCommand createShell() {
    //  ...
    // The encoding value here is best changed to be settable
    optCodepage.setName("WINRS_CODEPAGE");
    optCodepage.setValue("437");
    optSetCreate.getOption().add(optCodepage);

    ResourceCreated resourceCreated = winrm.create(shell, RESOURCE_URI, MAX_ENVELOPER_SIZE, operationTimeout, locale, optSetCreate);
    String shellId = getShellId(resourceCreated);

    return new ShellCommand(winrm, shellId, operationTimeout, retryReceiveAfterOperationTimeout, locale);
}

`

ShellCommand.java
`

private void getStreams(ReceiveResponse receiveResponse, Writer out, Writer err) {
    List<StreamType> streams = receiveResponse.getStream();
    for (StreamType s : streams) {
        byte[] value = s.getValue();
        if (value == null) continue;
        if (out != null && "stdout".equals(s.getName())) {
            try {
                //TODO use passed locale?
                if (value.length > 0) {
                    // Here it is best to use GBK encoding by default: new String(value, "GBK"), or you can set to use the specified encoding
                    out.write(new String(value));
                    out.flush();
                }
                if (Boolean.TRUE.equals(s.isEnd())) {
                    out.close();
                }
            } catch (IOException e) {
                throw new IllegalStateException(e);
            }
        }
        if (err != null && "stderr".equals(s.getName())) {
            try {
                //TODO use passed locale?
                if (value.length > 0) {
                    // Same here as above
                    err.write(new String(value));
                    err.flush();
                }
                if (Boolean.TRUE.equals(s.isEnd())) {
                    err.close();
                }
            } catch (IOException e) {
                throw new IllegalStateException(e);
            }
        }
    }
}

Hi @lnkForKing this sounds like a good improvement.
We are planning to make a new release later this year with Java 11 compatibility. I'll this to the backlog for that moment.
Fell free to open a PR with your code
