Php generates Chinese garbled QR codes _ PHP Tutorial

Php generates Chinese garbled QR codes. Php generates QR code with Chinese garbled characters. Recently, a project has been run to scan the QR code to get vcard. some generated QR codes have encountered a problem, what should I do if I have to use php to generate a QR code with Chinese garbled characters after scanning on my android mobile phone?

Recently, I had a project to scan the QR code to get the vcard. I encountered a problem. some of the generated QR codes were garbled in the Chinese names in the vcard obtained after scanning with the android mobile phone, after comparison, we found that there is no content in the ORG type in this part of vcard, and a fixed string is added when no content is determined, so that the garbled problem can be solved. This solution is a curve to save the country. I don't know how to solve the garbled code problem. please leave a message if you can find a solution. thank you.
