Question

As title say …
I read content from htto response

 

    InputStream is = response.getEntity().getContent();
    String cw = IOUtils.toString(is);
    byte[] b = cw.getBytes("Cp1250");
    String x = StringUtils.newStringUtf8(b);
    String content = new String(b, "UTF-8");

    System.out.println(content);

 

I have tried plenty of variations. I am little confused about what are correct encoding constants used as strings. windows-1250 or Cp1250. UTF-8 or utf-8 or utf8?

You seem to think that a String object has an encoding. That’s not correct. An encoding is used as part of the translation from binary data (a byte[] or InputStream) to text data (a String or char[] etc).

It’s not clear what IOUtils.toString is doing, but it’s almost certainly losing data or at least handling it inappropriately. If your data is originally in Windows-1250, then you should use an InputStreamReader wrapping the InputStream, specifying the charset in the InputStreamReader constructor call.

It’s not clear where UTF-8 comes in – you might want to write out the data in UTF-8 afterwards, but the result of that would be byte[], not a string.
