Hello.

I have a problem with the built-in QR code detection of a vCard 4.0 in iOS.

As described in https://tools.ietf.org/html/rfc6350 vCard Version 4.0 is always encoded with UTF-8. But it seems that the built-in QR code reader of iOS isn't able to decode the special characters correctly. Or am I missing something?

Here is an example. Encode it with any QR code generator in the Internet and point your iOS Camera app at it. You will see that all special characters are not displayed correctly.

BEGIN:VCARD

VERSION:4.0

This is just a workaround, but VCard 3.0 is parsed correctly.

BEGIN:VCARD

Hello,

The soluction is to force the encode, your code must be like this: BEGIN:VCARD VERSION:4.0 N;CHARSET=utf-8:T€st;Björn ORG:ÖÜÄ TEL;CELL:+12 (34) 567890 ADR;CHARSET=utf-8:;;Blà St.;Blè Town;;12345;ç-Land URL:https://www.test123.com EMAIL;WORK;INTERNET:mailexample END:VCARD

I hope that it solve your issue
