Why can't I output qrcode?

[sunrabbit123]

Why not I get qrcode image?

I get only Unknown String

What is ploblem?

my OS is Windows 10
my python version is 3.9.0
my wifi-password version is 1.0.7

I am unsure of why this is happening. Maybe this is happening because your system's language is Latin a language. I don't use Windows so I unfortunately can't debug this error.

My ststem language is korean

But this doesn't matter in code.

We need more examples.

This is likely affecting all windows boxes, at least it does on mine aswell. It likely has to do with the symbols the qrcode library is sending. I dont believe the windows terminal is UTF-8, therefore UTF-8 specific symbols dont display properly like they do on Mac and Linux. However in testing this I also noticed that outputting to image might also be broken? At least it is for me.

@sdushantha I think this might be an issue of the qrcode.print_tty() function. The next best thing in Windows might be their print_ascii function but I havent tested it

Confirmation of it being broken on mine:

@sunrabbit123 @littlediobolic I think I found a solution to this issue.

In the beginning of the main function, could you add this code:

import colorama
colorama.init()

This will emulate support for ANSI escape sequences, which is needed in order to display the QR code.

If you don't have colorama installed, you'll have to install it through pip:

python3 -m pip install --user colorama

Your solution works very sexy.

However, it would be better to write the phrase in generate_qr_code rather than main.

ex:

def generate_qr_code(ssid, password, image=False):
    # Source: https://git.io/JtLIv
    text = f"WIFI:T:WPA;S:{ssid};P:{password};;"

    qr = qrcode.QRCode(version=2,
                       error_correction=qrcode.constants.ERROR_CORRECT_L,
                       box_size=10,
                       border=4)
    qr.add_data(text)

    if image:
        file_name = ssid.replace(" ", "_") + ".png"
        img = qr.make_image()
        img.save(file_name)
        print(f"QR code has been saved to {file_name}")
        os.system(file_name)
    else:
        import colorama
        colorama.init()
        qr.make()
        qr.print_tty()
