Beschreibung
I'm seeing this with version 1.6.5 on Ubuntu 16.04 (xenial).
Below is a trivial test program . (It requires the German locale to be installed.)
With the line that sets the locale commented out (assuming your are in a locale that uses '.' as the decimal point), everything works fine. With the locale setting enabled, the call fails and the error message is
'3.14' is not a number.
There is a related discussion in bug #283, but the issue below is different, I believe.
#include <jsoncpp/json/reader.h>
#include <iostream>
#include <locale>
int main(int, char **)
{
using namespace std;
locale::global(locale("de_DE.utf8"));
Json::Value root;
Json::CharReaderBuilder rbuilder;
rbuilder["collectComments"] = false;
string json_string = "3.14";
unique_ptr<Json::CharReader> reader(rbuilder.newCharReader());
auto begin = json_string.c_str();
auto end = json_string.c_str() + json_string.size();
string errors;
bool ok = reader->parse(begin, end, &root, &errors);
if (!ok)
{
cerr << errors << endl;
}
}
