Transcodes an array of unicode characters to an array of codepage characters. The source pointer is an I/O parameter, it starts out pointing where the function is to begin transcoding, and ends up pointing after the first sequence of the bytes that it encounters that are semantically invalid. if ucnv_setToUCallBack is called with an action other than STOP before a call is made to this API, consumed and source should point to the same place (unless target ends with an imcomplete sequence of bytes and flush is FALSE). the target buffer buffer needs to be a least the size of the maximum # of bytes per characters allowed by the target codepage.
