Let's continue my articles about integer overflows in Go.
Here are examples
var a int var b uint8 a = 255 + 1 b = uint8(a) fmt.Println(b) // 0 conversion overflow a = -1 b = uint8(a) fmt.Println(b) // 255 conversion overflow c, d := 255, 300 res := int8(max(c, d)) fmt.Println(res) // 44 str := "\x99" // hexadecimal representation of Trademark ASCII character: ™ fmt.Println(str[0]) // 153 fmt.Println(int8(str[0])) // -103

Small correction: the trademark character is not in ASCII since ASCII is only 7-bit. The string "\x99" is not a valid UTF-8 encoding either; so it is simply a string that contains the byte 153
Indeed, thanks
