我正在尝试将对象中的String变量赋值给一个值，该值可能包含丹麦字母，包括æ，ø和å。我正试图将它传递给我已经运行的服务器，但似乎所有这些字符在我将它们分配给字符串时就变成了thus，因此“HælløWærld”变成了“H ll ” WRLD”。字符编码是否默认为无法在Android中处理这些字符的内容？
上传字符串的代码：
url = new URL(restUrl);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("POST");
urlConnection.setDoOutput(true);
urlConnection.setDoInput(true);
OutputStream outputStream = urlConnection.getOutputStream();
// TODO might have to change this to other charset to preserve æ ø å
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));
String test = getQuery(postParams);
Log.d("Parametere", test);
writer.write(test);
writer.flush();
writer.close();
outputStream.close();
responseCode = urlConnection.getResponseCode();
urlConnection.disconnect();
getQuery的位置是：
private String getQuery(ArrayList<NameValuePair> params) throws UnsupportedEncodingException {
StringBuilder result = new StringBuilder();
boolean first = true;
for (NameValuePair pair : params) {
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(pair.getName(), "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(pair.getValue(), "UTF-8"));
}
return result.toString();
}

我也知道这很容易被SQL注入和所有好东西，但这是一个大学项目，所以我真的不太关心。
