// read_line_utf8 blocks execution in a loop and awaits user input
// characters from a terminal until `EOF` or `Enter` key is encountered
// in the input stream.
// read_line_utf8 returns the complete input line as an UTF-8 encoded `[]rune` or
// an error if the line is empty.
// The `prompt` `string` is output as a prefix text for the input capturing.
// read_line_utf8 is the main method of the `readline` module and `Readline` struct.
