Unicode characters in barcode

Most barcode standards have not specified how to encode Unicode characters into barcode symbologies. However matrix (2d) barcodes usually support barcode data encoding with byte array data mode.

Now most of the 2d barcode generator library or software will automatically convert Unicode chars into byte array using UTF-8 encoding mode, and encode barcodes with byte array data mode.

During decoding barcode image using barcode reader software or device, C# developer could read byte array data from 2d barcode symbols, and decode the byte array into string with Unicode text using the same character encoding mode.
