As I found we can legaly treat `char*` as the object of type `char` but not as an array of objects. This is mentioned in http://eel.is/c++draft/basic.compound#3.4 //For purposes of pointer arithmetic ... an object of type T that is not an array element is considered to belong to an array with one element of type T.// That means that we can get only the first element of `char*`, otherwise it would be an UB.
