Getting ASCII character warning

I have the following line of code to help me draw the screen

Code:

---

    char topLeft = 201;
    char horizontalLines = 205;
    char topRight = 187;
    char verticalLines = 186;
    char bottomLeft = 200;
    char bottomRight = 188;

---

these characters are from here. But now i get warnings

Code:

---

warning C4309: 'initializing' : truncation of constant value

---

Is there a way i can avoid this warning?

A 'char' type may either be signed or unsigned, that is implementation dependent. It is apparently signed in your implementation, meaning the maximum value is 127. You'll need to use 'unsigned char' to be able to store one-byte values which most often have 8 bits.

In VS, all chars are signed by default.
