  • Created QR Code is compatible with industry criteria and international standards
VB.NET QR Code Generation - Unicode Overview
Unicode is a character encoding standard that has widespread acceptance. It provides a unique number for every character, no matter what the platform or the program or the language that users are using.
As we know, QR Code has a huge potential to store large amount of information and the information can be encoded in both 2-byte & 1-byte characters. For the common QR Code barcode generators in the market, they can only encode 1-byte data strings. But VB.NET QR Code barcode generator control from Barcodelib.com offers .NET developers a mature barcoding solution to encode data characters from other languages, like Chinese, Korean, using 2-byte data strings, namely, Unicode.
QR Code Unicode Encodeing for VB.NET Class
QR Code can encode large amount of information, including the normal ASCII range and other special characters, like Arabic, Chinese, Hebrew, Hindi, Japanese & Korean.
And BarcodeLib.com's QR Code VB.NET barcode generation library is able to encode those special character sets though encoding Unicode. In order to encode Unicode strings in those languages, you need to do conversions in the process of VB.NET QR Code generation & QR Code recognition.

How to Use Base64[] Conversion for QR Code Unicode Encoding in VB.NET

In this section, we will provide you some sample VB.NET code on how to encode Unicode when generating QR Code barcode images.

How to Obtain the Original Unicode String During QR Code Recognition

As VB.NET class code above uses Base64[] conversion method to encode Unicode. Therefore, to read & get the original data, you need to convert the decoded data to original data via Base64[] conversion. The following is VB.NET code for achieve that.
     byte[] base64SingleBytes = Convert.FromBase64String(data);
     string UnicodeFromBarcode = System.Text.Encoding.Unicode.GetString(base64SingleBytes);
Other 2D Barcodes Supporting VB.NET Unicode Encodation
Apart from support encoding Unicode into QR Code, VB.NET Barcode Generator from BarcodeLib.com is also able to encode Unicode into other 2D barcode types, like PDF-417 & Data Matrix.
For C# QR Code Unicode Encoding, you may see C# QR Code Barcode Unicode Encoding Guide.
Other Barcode SDKs Supports 2D Barcode Unicode Encoding
Besides Barcode Generator Suite for .NET, VB.NET, we also provides the following barcode generator SDKs that supports 2D barcode Unicode encoding.
