Truncating Strings by Bytes

Question

        String truncatedValue = \"\";
        String curren         


        

Answer 1

The more sane solution is using decoder:

final Charset CHARSET = Charset.forName("UTF-8"); // or any other charset
final byte[] bytes = inputString.getBytes(CHARSET);
final CharsetDecoder decoder = CHARSET.newDecoder();
decoder.onMalformedInput(CodingErrorAction.IGNORE);
decoder.reset();
final CharBuffer decoded = decoder.decode(ByteBuffer.wrap(bytes, 0, limit));
final String outputString = decoded.toString();
