 // 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.
