第一次遇到这种“stray '\342' in program”的错误。

下面是我的代码

#include <bits/stdc++.h>

using namespace std;

#define sc(n) scanf("%d",&n)
#define tc1 cin>>t;while(t--)
#define forf(i, a, b) for(i =(a); i <(b); ++i)

int main()
{
long long int t, x1, x2, x3, y1, y2, y3, points, temp;

float area;
tc1
{
cin >> x1 >> y1 >> x2 >> y2 >> x3 >> y3;
temp = x1*y2 + x2*y3 + x3*y1 −x1*y3 − x3*y2 − x2*y1;
area = 0.5f * abs(temp);
points = area + 1 - (3/2);
cout << points << "\n";
}
return 0;
}

下面是我的编译错误:

solution.cc:18:9: error: stray '\342' in program
temp=x1*y2 +x2*y3 + x3*y1 −x1*y3 − x3*y2 − x2*y1;
^

temp=x1*y2 +x2*y3 + x3*y1 −x1*y3 − x3*y2 − x2*y1;
^

这个错误是什么意思?

我无法通过之前回答的问题理解此错误的确切含义。
