vCard from E-mail Signature

vCard from E-mail Signature — Turns the signature block of an e-mail (English, Bulgarian, German or another language) into a vCard 4.0 contact card, answered as the card text only. Follows RFC 6350 where plain models slip - VERSION:4.0 right after BEGIN, FN always present, N with exactly five components, ADR with exactly seven, commas, semicolons and backslashes escaped in text values, phone numbers as tel URIs. What the signature does not say stays out - no invented surname, no guessed country…
