Hi,

I'm playing with new boost library property_tree. And I have several questions regarding it. 1) Suppose there is xml file with utf8 encoding. What is the best way to populate it into wptree?

Parse from a wistream that has been imbued with a locale containing a UTF-8 conversion facet, e.g. the one from Boost.Serialization.

2) How can I save wptree into xml file with utf8 encoding. Unfortunately write_xml requires wostream.

Same as above.

3) Is there something like map operator[]? I.e. I need the following behavior: wptree & something(some_path) { boost::optional child = my_tree.get_child(some_path); if(child) return child.get(); else return my_tree.put_child(some_path); }

I don't think there is such a thing available, but it sounds useful. I'll see about adding it. Sebastian
