XML_Tree Encoding

Hello. It has been indebted very much at your result. It is a question about XML_Tree. Except for ASCII Although he wants to draw up an XML document, in the present condition, it seems to be unable to do. Is there any schedule which will correspond from now on? As an example, it is about text declaration in XML_Tree and XML entities Escape in XML_Tree_Node. Especially, sanitize for ascii is visible to giving me in the 2-byte area (Japanese) too much. This thinks that it is what a class user should perform. -- ysano
