Implement support for Chinese symbols. Currently, if you enter the barcode Text in Chinese, the value will be coerced to to an empty string and nothing will be rendered.
There are solutions posted on the Telerik forums about how to accomplish this using styles but it would save people a lot of time and work (especially if they are using several barcode types) if there was a Boolean property that could be set to hide or display the barcode text (much like the RenderChecksum property is used to hide or display the checksum for the barcode)
Implement Intelligent Mail Barcode type.
