Answer

I think you might be

🇬🇷, or the flag of Greece.

As others have pointed out,

in the code there is a Greek question mark, and also ⚑, so a flag, can be found by putting together the values of x, y and the comment. Furthermore, others have found the mistakes spelling out "Minus". However, also the space and the question mark on the end should be a period, so this would make the message "Minus ?". So the complete result is "Greek question mark flag minus ?", making "Greek flag".
