Erroneous character encoding when line is wrapped according to lineLength #80
Description
Characters are encoded by two bytes In Russian: =D0=A2=D0=B0=D0=BC=D0=B0=D1=80=D0=B0 for Тамара. Your writer for some reason might wrap the line in the middle of encoded string: =D0=A2=D0=B0=D0=BC=D0=B0=D1=80=D0\n=B0. The last string won't be decoded by Google Contacts importer, for example. It would be Тамар� � instead.
