Hi All, I have encounter an bug in Boost.PropertyTree and submit a patch to fix this bug 3 month ago: https://svn.boost.org/trac/boost/ticket/4340 Below is a brief description: ---------------------------------------------------------- boost::property_tree::read_xml(wistream&, wptree&) throw exception if tag/value/attribute has a unicode with '\0' inside, for example, for unicode char L'\u4E00', an exception will be throw because the parser treat L'\u4E00' as '\0'. The following test case reproduce the bug: BOOST_AUTO_TEST_CASE(test_i18n_xml_tag_name) { wistringstream in(L"<\u4E00>abc</\u4E00>"); property_tree::wptree pt; BOOST_REQUIRE_NO_THROW(property_tree::read_xml(in, pt)); BOOST_CHECK(L"abc" == pt.get<wstring>(L"\u4E00")); } ---------------------------------------------------------------- This ticket have been sleeping for 3 month, I'm wondering if someone could help review it and apply the patch to the trunk or just fix it in another way. More generally, what's the boost policy for maintain the existing library, especially regarding for the bug fix. Best Regards, Qiang http://zhuoqiang.me
