// A value of type [u]int8_t is treated as a character when being put to an
// output stream, which can result in invisible characters being printed. To
// avoid that, such a value needs to be casted to a wider type. It can be done
// by using the following template to find a target type to cast our value to.
// NOTE: There is a preprocessor macro below which can be used instead of the
// tedious typename stuff.
