External references, such as a standards document, or specification? http://blog.publicobject.com/2010/08/handling-byte-order-mark-in-java.html copied here (in case that blog goes away):

public Reader inputStreamToReader(InputStream in) throws IOException {
in.mark(3);
int byte1 = in.read();
int byte2 = in.read();
if (byte1 == 0xFF && byte2 == 0xFE) {
return new InputStreamReader(in, "UTF-16LE");
} else if (byte1 == 0xFF && byte2 == 0xFF) {
return new InputStreamReader(in, "UTF-16BE");
} else {
int byte3 = in.read();
if (byte1 == 0xEF && byte2 == 0xBB && byte3 == 0xBF) {
return new InputStreamReader(in, "UTF-8");
} else {
in.reset();
return new InputStreamReader(in);
}
}
} Java environments (e.g. Java 6, Android 2.3, App Engine 1.4.3, or All)? All Please describe the feature requested. Currently the GSON library implementation only supports UTF-8. The algorithm above could potentially be used for supporting the other 3 Unicode encodings supported by the JSON specifications.
