How i can to compare two TCHAR in C++?

Hallo! i’ve some FString, and i get from it TCHAR by index. How i can compare it with other TCHAR?

FString str = "Hallo my little World";

 bool getCh(int x, TCHAR ch) {
	return (FCString::Strcmp(&str[x], ch)!=0);
 }

And in other script i call method getCh(…) something like this “getCh(1, ‘q’)” hoping to get true or false. BUT THIS DON’T WORK! ;-(
