quoted-printable encoded entities are not correctly converted #112

Closed j-ed closed 3 years ago

j-ed commented 3 years ago

The vCard 2.1 format allows to use quoted-printable encoded entities, which aren't allowed to be used in vCard 3.0/4.0 anymore.

If the library is used to convert a contact record from the vCard2.1 to the vCard 3.0 format the quoted-printable entities are currently kept and not decoded/converted correctly. This causes problems when international characters are used in, e.g. names, and usually prevents an app from importing data correctly. CC: @AndyScherzinger @tobiasKaminsky
