Hi, first of all thanks for you lib.

I have exported my contacts from the default contact app on an android phone (lineagos 21 enchiladas) and each time a field have an accent or a non-ascii character the file with have its content formatted as follow:

TITLE;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:=4B=69=6E=C3=A9=73=69=74=68=C3=A9=72=61=70=65=75=74=65

For example this field TITLE field contains Kinésithérapeute as value. As you have probably guessed, when I parse it with you lib it will print directly the content without decoding.

The RFC6350 section 3.1 make a reference to the RFC3536 which have a reference to the QUOTED-PRINTABLE notation.
