Question about detect if RMTES_STRING failed to encode

@Carfield Yim

Can you print the raw bytes hex data when the exception occurred?

We would like to check the data in the buffer.

That string is also useful but I would like to see the raw data.

You can try the one mentioned on the StackOverflow.

Do you mean the hex values are "0x44 0x51 0x1B" and "0x51 0x20 0x1B"?

Did the library fail to decode these values?

@Carfield Yim

I tested with the following code.

	public static void main(String[] args) {

		// TODO Auto-generated method stub

		byte[] bytes1 = HexFormat.of().parseHex("44511B");

		byte[] bytes2 = HexFormat.of().parseHex("51201B");


		String dataDisplay = new String(bytes2, new RmtesCharsetProvider().charsetForName("RMTES"));



	}

I also got the exception.

You may need to contact the ACTIV data provider to verify those values.

@Carfield Yim

It could be an enhancement request that should be submitted to the API support team via Contact Premium Support.

However, the application can catch the error.

		try {

			String dataDisplay = new String(bytes2, new RmtesCharsetProvider().charsetForName("RMTES"));

		}catch (java.nio.charset.CoderMalfunctionError ex) {

			System.out.println("Exception:");

			System.out.println(ex.getMessage());

		}
