I'm using libxode to make string to XMLnode. Sometime I use 2byte charactor,(ex: japanese, korean) in XML, ex) <jab> <data>(2byte charactor)</data> </jab> When I put english instead of 2byte charactor, xmlnode_str() works well. But if I use 2byte charactor, It works terrable, always return NULL. How can I solve this problem,?
