I would like to ask you a question. The QR code was made two years ago. At that time, WeChat could scan it. Now the following code appears when scanning. The version number of phpqrcode is 1.1.4. It can be scanned using UC browser, but not WeChat. Please tell me how to deal with it, thank you. (The picture below is an example)

After testing on the phpqrcode official website, once the content is in Chinese, WeChat scanning will not work. Official website http://phpqrcode.sourceforge.net/
