bytes.ToUpperSpecial()

The ToUpperSpecial() function is an inbuilt function of the bytes package which is used to get a copy of the byte slice (s – treated as UTF-8-encoded bytes) with all the Unicode letters mapped to their upper case, giving priority to the special casing rules.

It accepts two parameters (c unicode.SpecialCase, s []byte) and returns a copy with all the Unicode letters mapped to their upper case.

Syntax:

func ToUpperSpecial(c unicode.SpecialCase, s []byte) []byte

Parameter(s):

• c : Space case.
• s : The byte slice to be used to create a copy of the uppercase byte slice.

Return Value:

The return type of the bytes.ToUpperSpecial() function is a []byte, it returns a copy with all the Unicode letters mapped to their upper case.

Example 1:

// Golang program to demonstrate the
// example of bytes.ToUpperSpecial() function

package main

import (
	"bytes"
	"fmt"
	"unicode"
)

func main() {
	fmt.Printf("%s\n", bytes.ToUpperSpecial(
		unicode.AzeriCase, []byte("Every moment is a fresh beginning.")))
	fmt.Printf("%s\n", bytes.ToUpperSpecial(
		unicode.AzeriCase, []byte("merhaba dünya, nasılsın?")))
	fmt.Printf("%s\n", bytes.ToUpperSpecial(
		unicode.AzeriCase, []byte("Be so good they can't ignore you.")))
}

Output:

EVERY MOMENT İS A FRESH BEGİNNİNG.
MERHABA DÜNYA, NASILSIN?
BE SO GOOD THEY CAN'T İGNORE YOU.

Example 2:

// Golang program to demonstrate the
// example of bytes.ToUpperSpecial() function

package main

import (
	"bytes"
	"fmt"
	"unicode"
)

func main() {
	var str []byte
	var result []byte

	str = []byte("Every moment is a fresh beginning.")
	result = bytes.ToUpperSpecial(unicode.AzeriCase, str)
	fmt.Printf("Original string: %s\n", str)
	fmt.Printf("Uppercase string: %s\n", result)
	fmt.Println()

	str = []byte("merhaba dünya, nasılsın?")
	result = bytes.ToUpperSpecial(unicode.AzeriCase, str)
	fmt.Printf("Original string: %s\n", str)
	fmt.Printf("Uppercase string: %s\n", result)
	fmt.Println()

	str = []byte("Be so good they can't ignore you.")
	result = bytes.ToUpperSpecial(unicode.AzeriCase, str)
	fmt.Printf("Original string: %s\n", str)
	fmt.Printf("Uppercase string: %s\n", result)
}

Output:

Original string: Every moment is a fresh beginning.
Uppercase string: EVERY MOMENT İS A FRESH BEGİNNİNG.

Original string: merhaba dünya, nasılsın?
Uppercase string: MERHABA DÜNYA, NASILSIN?

Original string: Be so good they can't ignore you.
Uppercase string: BE SO GOOD THEY CAN'T İGNORE YOU.
