Swedish letter in QR code

[Misha]

Try to generate QR code, try add Swedish letter and got wrong QR code (with red pixels LOL)

generateQR("Övrigt asdasd asdas djaskl djaslk djaslkj dlaiodqjwiodjaskldj aksldjlk Övrigt")

    func generateQR(QRText string) {
        qrc, err := qrcode.New(QRText)
        if err != nil {
	        fmt.Printf("could not generate QRCode: %v", err)
        }
    
        // save file
        if err := qrc.Save("qr.png"); err != nil {
	        fmt.Printf("could not save image: %v", err)
        }
    }

what happened ... orz, give me some time to figure out

@mishanon after some tests, this bug would be triggered while input content is more than 74 characters, it's not related to the character set (Swedish), but I don't locate the bug in the source code yet. I will keep working on it. In my oppinion, it's version's bug...

[yeqown]

@mishanon fixed in v1.5.2.

There is a bug while the raw content's length and error-correcting level require a higher version (6+):

1. I didn't code all QR Code version alignment patterns.
2. the function fillVersionInfo which works only version 7+ didn't work as QR Code specification.

By the way, this library didn't support Kanji encoding and all after it, https://en.wikipedia.org/wiki/QR_code#Encoding, but Byte encoding supports ISO-8859 character set which includes Swedish letters.

Thanks for your feedback.
