node-vcard quoted-printable not handled correctly

My Source data (from sipgate.de API, extended by VERSION:2.1\r\n):

BEGIN:VCARD\r\nVERSION:2.1\r\nFN;quoted-printable:Peter Pan\r\nNOTE;quoted-printable:\r\nTEL;cell:+49123123123123\r\nEND:VCARD

This is always treated as invalid data because the validator cannot find a FN entry. But it's present with a semicolon and quoted-printable which is valid I think (as of http://www.imc.org/pdi/vcard-21.txt).

Can you share the version you solved?

Wohoo this is an old one. I cannot remember how I solved it. The script I was using is not active anymore.
