How I can transform bytes[] to String[] in format HEX without losing "CE" chars in the picture?

Answer 1

If your bytes are just plain text, then you can do

new String(bytes, "UTF-8");

If your bytes create a hex string, convert that hex string to another byte[] by doing

new String(DatatypeConverter.parseHexBinary(new String(bytes)), "UTF-8")
