hi, all
I met a strange error of charset encoding, see below code:
public class CharsetMain extends Activity {
private final static String LOG_TAG = "zzw";
final String s123="1我2"; // at least one none-ascii
final String sabc="abcdef";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(LOG_TAG, sabc); // ok
// set charset input to sabc
sabc.getBytes();
// fill charset input with s123
Charset charset = java.nio.charset.Charset.forName("UTF-8");
charset.encode(s123);
Log.d(LOG_TAG, sabc); // bad
Log.d(LOG_TAG, "abcdef"); // bad
finish();
}
}
string s123 contains a Chinese character, the last 2 log gives a bad
result, the string sabc is filled with string s123.
I found the error is at com.ibm.icu4jni.charset.CharsetEncoderICU,
method getArray, about line 342.
it saves the internal buffer of input string, or just copy the input
string to it saved buffer, if 2 continuous calls are just the 2
conditions, the later will copy the input string to the buffer of 1st
string.
I am not sure it's a bug, but it cases Email program runs abnormally
with Chinese local.
any idea? any comments are appreciated, thanks
