I need more information:

• How does the file you want to read look like?
• What is the code you execute to read the file?
• Which function is called when the exception is raised?
• Do you have a backtrace?

[raoul632]

my json file look like this :
{
"page_1":{
"texte":"vous êtes sur un chemin en terre battus la lumiere vous ebloui mais vous pouvez voir cette etrange porte",
"actions":{
"move_to":2
}
}
}

the code to read :
std::ifstream ifs("livre.json");
json jf = json::parse(ifs); <-- the function parse raise this exception

the backtrace (where is stoping in the stack ) :

ConsoleApplication1.exe!nlohmann::detail::json_sax_dom_parser<nlohmann::basic_json<std::map,std::vector,std::string,bool,__int64,unsigned __int64,double,std::allocator,nlohmann::adl_serializer,std::vector<unsigned char,std::allocator>>>::parse_error(unsigned int __formal, const std::string & __formal, const nlohmann::detail::exception & ex) Ligne 4982 C++

Is the JSON file UTF-8 encoded?

[raoul632]

you find the problem. sorry
its encoded in ansi by default

[nlohmann]

Could you send me the file or attach it? I tried to reproduce the error locally, but only got this exception if I save the JSON you mentioned with non-UTF-8 encoding:

[json.exception.parse_error.101] parse error at line 3, column 25: syntax error while parsing value - invalid string: ill-formed UTF-8 byte; last read: '"vous \352t'

I did not get a out_of_range exception.

[raoul632]

sorry i didn't see the notification :
i can crash with this file
livre.zip

[nlohmann]

Thanks. I again get this error:

[json.exception.parse_error.101] parse error at line 3, column 24: syntax error while parsing value - invalid string: ill-formed UTF-8 byte; last read: '"vous \352t'
