Rune is a superset of ASCII or it is an alias of int32. It holds all the characters available in the world’s writing system, including accents and other diacritical marks, control codes like tab and carriage return, and assigns each one a standard number. This standard number is known as a Unicode code point or rune in the Go language.
You are allowed to map the given rune into the upper case with the help of ToUpper() function. This function changes the case of the given rune(if the case of the rune is lower or title) into upper case and if the given rune is already present in upper case, then this function does nothing. This function is defined under Unicode package, so for accessing this method you need to import the Unicode package in your program.
