import - OSX C++ Xcode: Pasting long input into console gives upside down question marks -

-

we've made program takes long string of tab-delimited input pasted console window , splits correct variables. however, lately long strings of metadata, bunch of upside down question marks have appeared - after has been pasted in, before, , both... here screenshots of when paste in bunch of filler numbers: 1000 characters almost 1200 characters 1400 characters

it doesn't appear terribly consistent upside down question marks appear. pasting in normal english metadata, no special characters or other languages.

here code getting information:

string faimport; cin.ignore(1000, '\n'); cout << "\nplease copy , paste information finding aid , press enter: \n"; getline(cin, faimport); cout << faimport;

i still don't know why problem exists, looks there character limit of around 1000 xcode...

i switched on visual studio on pc , worked perfectly...
