\nThe info on what encoding your text was is not a part of the raw bytes. This means that you are responsible for saving and restoring the encoding if you are working with text where you want to preserve encodings.<\/span><\/p>\n
\n1. Save the Encoding of the text that you are about to Encrypt.<\/span>
\n2. Encrypt the text. (Remember once it is in encrypted form then you may never ever tamper with the encoding).<\/span><\/p>\n
\n1. Decrypt the data.<\/span>
