Ok

I'm not sure to have good understood the vcard2.1: a logical line is composed with 4 parts (group, name, parameter list and value). Can the three first parts be folded ? If yes, with which method ?
How encode a N field (for example) which contains multiple additional names whose one contains a COMMA character or a SEMI-COLON character ? Must i add backslash, then use QP ?
