segno always append '0a' to the content about segno

[heuer]

Thanks for your report.

Can you provide an example (or a test case)?
Are you using the API or the command line script?
Which decoder do you use?

Thanks.

Thank you for your reply!

This is my code:
import sys
import segno
qr = segno.make('0H450116721300010000001-010010000000000011842118', version=7, error='H')
qr.save('H.png', scale=5)

And I decode H.png by https://www.onlinebarcodereader.com/, the following image is the result.

The correct result should be:

Thanks for your explanation. As I see it, the output (see "content" box) is correct (your screenshot does not show the complete box).

IMO it's a problem of the webservice and not a Segno issue. You can try QR codes generated by other libs (I used PyQRCode and libqrencode) and you'll always get the same result.

Yes. It looks right, but in fact sengo append a "\n" to the content. We can find a '0a' in the end of the hex values and it's a "\n" ( hex(ord('\n')) = 0xa ).

but in fact sengo append a "\n" to the content.

I guess the webservice adds it while decoding or presenting the hex code.

As written, the webservice always adds 0a regardless which QR code lib I tried.
Please try another QR code lib and you'll see that it adds the 0a to the result.

Here the result of another decoder (ZXing):

OK. I'll try it. Thank you very much.
