data decode is Garbled

[wydonglove]

After do method of "scan_codes" to a picture, i decode data to "utf-8" or "gbk",but both garbled. the target language is chinese. why , and how to reslove it, thanks

Hi,

Can you provide us with an example image and the resulting output?

[wydonglove]

that is a QR code picture 。 this is my code. ######### codes = zbarlight.scan_codes(['qrcode'],image) item = [] for code in codes: print("type(code):{},code:{}".format(type(code),code)) basetr_0 = code.decode('utf-8')

basetr1 = code.decode('GBK')

print("basetr0：%s" % basetr_0)

##########

the print is show below:

type(code):<class 'bytes'>,code:b'\xc3\x90\xc3\xad\xc2\xbf\xc3\x89\xc3\x96\xc2\xa4\xc2\xba\xc3\x85: JY25101850025950\n\r\xc2\xbe\xc2\xad\xc3\x93\xc2\xaa\xc3\x95\xc3\x9f\xc3\x83\xc3\xbb\xc2\xb3\xc3\x86: \xc3\x8c\xc3\xac\xc2\xb8\xc2\xae\xc3\x90\xc3\x82\xc3\x87\xc3\xb8\xc2\xb3\xc3\x89\xc2\xb6\xc2\xbc\xc3\x86\xc2\xac\xc3\x87\xc3\xb8\xc2\xbb\xc2\xaa\xc3\x91\xc3\xb4\xc3\x9f\xc2\xa3\xc2\xb0\xc3\x8d\xc3\x8a\xc3\x8a\xc2\xb4\xc2\xa8\xc3\x8f\xc3\xa3\xc3\x82\xc3\xa8\xc3\x82\xc3\xa8\xc2\xb2\xc3\x8b\xc2\xb2\xc3\x8d\xc2\xb9\xc3\x9d\n\r\xc3\x89\xc3\xa7\xc2\xbb\xc3\xa1\xc3\x90\xc3\x85\xc3\x93\xc3\x83\xc2\xb4\xc3\xba\xc3\x82\xc3\xab: 92510100MA6CQUTG8C\n\r\xc2\xb7\xc2\xa8\xc2\xb6\xc2\xa8\xc2\xb4\xc3\xba\xc2\xb1\xc3\xad\xc3\x88\xc3\x8b(\xc2\xb8\xc2\xba\xc3\x94\xc3\xb0\xc3\x88\xc3\x8b): \xc2\xb3\xc3\x82\xc3\xa8\xc3\xab\n\r\xc3\x93\xc3\x90\xc3\x90\xc2\xa7\xc3\x86\xc3\x9a\xc3\x8f\xc3\x9e: 2022\xc3\x84\xc3\xaa09\xc3\x94\xc3\x8224\xc3\x88\xc3\x95\n\r\xc3\x88\xc3\x95\xc2\xb3\xc2\xa3\xc2\xbc\xc3\xa0\xc2\xb6\xc2\xbd\xc2\xb9\xc3\x9c\xc3\x80\xc3\xad\xc3\x88\xc3\x8b\xc3\x94\xc2\xb1:\xc2\xb8\xc3\x9f\xc2\xbc\xc3\x91 \xc2\xbd\xc2\xad\xc3\x8e\xc3\x84\n\r\xc3\x87\xc2\xa9\xc2\xb7\xc2\xa2\xc3\x88\xc3\x8b:\xc3\x80\xc3\xae\xc2\xb2\xc2\xa8' basetr0：Ðí¿ÉÖ¤ºÅ: JY25101850025950 ¾­ÓªÕßÃû³Æ: Ì츮ÐÂÇø³É¶¼Æ¬Çø»ªÑôߣ°ÍÊÊ´¨ÏãÂèÂè²Ë²Í¹Ý Éç»áÐÅÓôúÂë: 92510100MA6CQUTG8C ·¨¶¨´ú±íÈË(¸ºÔðÈË): ³Âèë ÓÐЧÆÚÏÞ: 2022Äê09ÔÂ24ÈÕ ÈÕ³£¼à¶½¹ÜÀíÈËÔ±:¸ß¼Ñ ½­ÎÄ Ç©·¢ÈË:À

i covent bytes to str("utf-8") , the result should be chinese,but garbled

It looks like your data is not encoded in UTF-8, but in the GBK encoding:

>>> print(raw.decode('gbk'))

“gbk” encoding is also incorrect . """脨铆驴脡脰陇潞脜: JY25101850025950 ...." is garbled. the correct content is : 许可证号: JY25101850025950 经营者名称: 天府新区成都片区华阳撸巴适川香妈妈菜餐馆 .......

Oh, that's a problem.

Based on your input, I think you should find a clear declaration of the expected encoding for the QRCode; it seems that you're looking for an encoding that would encode CJK characters on 32 bits.

The fact that the "ascii" part went through properly would indicate that the raw QRCode parsing went well; beyond that, I am unable to help with advanced encoding systems :/
