 Hi,
 I am having this problem with boost::property_tree::read_json since 1.59!
 My json tree looks like this (code attached):


 {{{
 static std::string reduced("{\n    \"pipename\":
 \"quantiser(decode_lut_string=<verbatim>\\u0000@\\u0000\200\\u0000<\\/verbatim>)\",\n
 \"raw\": {\n        \"type\": \"t\",\n        \"rank\": \"3\",\n
 \"shape\": {\n            \"dim\": \"256\",\n            \"dim\":
 \"128\",\n            \"dim\": \"128\"\n        }\n    },\n
 \"encoded\": {\n        \"bytes\": \"4194304\"\n    }\n}\n",296);
 }}}

 If you check, there is a section between <verbatim>..</verbatim> that I'd
 like to parse as is. the read_json method however throws an exception
 saying that:

 {{{
 <unspecified file>(4): invalid code sequence
 }}}

 my guess is, that the characters quoted above are non-utf8 and hence
 property_tree throws. Is this a bug or a feature?

 if it is a feature, i.e. property_tree is meant to only yield utf8 encoded
 strings, how would I store an arbitrary string in the property tree? NB.
 the string above works with boost 1.58 and older!

 Best,
 P
