non ascii characters #81

Open AntonMezger opened 3 years ago

There is some problem with special characters. It seems that special characters like é, ö, è, ü, etc. are not represented in the qr-image.

A minimal code example would be helpful.

>>> import pyqrcode
>>> pyqrcode.create('é, ö, è, ü').png('test.png', scale=10)

Result test

At least ZXing is able to decode it

Hi,

I downloaded PyQrCode-1.2.1

I toke your above example, it worked perfectly well when I scanned with QrBot on my Iphone. I had with the swiss PayEye scanner unknown characters. I will have to dig somewhere in.

Thanks

I see. Is PayEye somehow related to the European Payments Council Quick Response Codes (EPC QR Codes)?

The EPC QR Codes make special demands on the encoding.

Found it. PayEye is for reading Swiss QR Codes a variant of the EPC QR Codes.

If you're developing Swiss QR Code support with PyQRCode I recommend to switch to another lib, PyQRCode is not maintained anymore.

Shameless plug: Segno. ;) It supports EPC QR Codes (but no Swiss QR Codes): https://segno.readthedocs.io/en/latest/epc-qrcodes.html
