problems with umlauts in VCARDS

[Cluster2a]

Hey, if I am using an umlaut within a vcard and generating the QRcode :

BEGIN:VCARD
VERSION:4.0
PRODID:-//Sabre//Sabre VObject 4.5.0//EN
UID:sabre-vobject-e48beda0-3a29-448d-a253-ef110e528ea6
N:Doe;John;;;
NICKNAME:
ORG:;
ADR;TYPE=WORK:;Bachstraße 1;PLZ;City;;;
NOTE:
END:VCARD

QrCode::encoding('UTF-8')->generate($vCard);

The following QRcode is generated:

Checking this QRcode with https://zxing.org/w/decode, the QRcode seems to be alright:

But reading on an android phone will result in an error, and an iPhone will mess up the umlaut:

Is there any way around this? I am not quite sure where the mistake happens.

@Cluster2a Hello,

I have exactly the same issue. Do you by any chance remember how you solved it ?

Thanks !

I solved it. I simply used vcard v3 instead of v4.
