Datamatrix encoding


I would like to encode special characters like:
öäüéàè in a DataMatrix barcode

sample code with Aspose Java Barcode 7.0.0


BarCodeBuilder b = new BarCodeBuilder();







When I read the barecode (file in attachment) with this Tools:
Datamatrix Decoder Online

The message text is in CP-1252 encoded and not in UTF-8. Why?

Our extern device cannot the special characters recognized.

I cannot used this code:
How to Generate and Recognize Barcodes for UTF 8 (Unicode) Characters

The Barcode recognized is made with a extern device and I cannot used the Java Aspose Library for recognition.

Could you help me please.

Hi Imran,

Thank you for your answer.

Yes with ClearImage it's work perfectly. But if you look the line "Converted Character Set". You will see "Converted Character Set: ISO-8859-1" (see file in attachment)

Our device read the Barcode Input Text only in UTF-8 Format and cannot read in ISO-8859-1.

How can I Change the character set Encoding in UTF-8.

With Aspose Java Barcode 7.0 the method:
