We recently studied two large but disjoint classes of twisted open WZWstrings: the open-string sectors of the WZW orientation orbifolds and theso-called basic class of twisted open WZW strings. In this paper, we discuss{\it all T-dualizations} of the basic class to construct the {\it general}twisted open WZW string -- which includes the disjoint classes above as specialcases. For the general case, we give the {\it branes} and {\it twistednon-commutative geometry} at the classical level and the {\it twistedopen-string KZ equations} at the operator level. Many examples of the generalconstruction are discussed, including in particular the simple case of twistedfree-bosonic open strings. We also revisit the open-string sectors of thegeneral WZW orientation orbifold in further detail. For completeness, wefinally review the {\it general twisted boundary state equation} which providesa complementary description of the general twisted open WZW string.Comment: 74 pages, typos correcte
