Hi Giorgio,
Thanks for reminding the details.
When we designed the TsFile, we wanted to use UTF-8.
I checked the source code, sometimes we clearly claim "utf-8" (e.g., device
name and measurement name) but something we do not (e.g., data point value).
Maybe we should claim the encoding all the time to avoid potential bugs.
Besides, as my computer is utf-8 by default, the String in Java also uses
utf-8 (and I think that is why there is no issue on my computer)
see the test:
```java
import java.io.UnsupportedEncodingException;
import org.junit.Assert;
import org.junit.Test;
public class StringTest {
@Test
public void test() throws UnsupportedEncodingException {
System.out.println(System.getProperty("file.encoding")); //will print
"UTF-8"
String text = "Chinese中文";
byte[] bytes1 = text.getBytes("UTF-8");
byte[] bytes2 = text.getBytes();
byte[] bytes3 = text.getBytes("UTF-16");
Assert.assertArrayEquals(bytes2, bytes1); // true
Assert.assertArrayEquals(bytes2, bytes3); // false
}
}
```
Best,
